# 5 Best Shared SMS Inbox Services for Teams

> Five services that let a team share the login codes sent to one company number, with published prices, what each one leaves out, and where ours is not the right buy.

_By The Shared SMS Inbox team, Product. Published 2026-09-05, updated 2026-09-05. About 14 minutes to read._

A shared SMS inbox for verification codes is a company phone number whose incoming texts land in a web inbox several approved people can open, rather than on one colleague’s handset. What separates the real options is narrow: how the number is billed, how many people can read it, whether messages are kept, which countries it covers, and what kind of number it is.

**Pricing and product information checked: September 2026.** Every figure below was read from the vendor’s own published pages. Where a vendor publishes nothing, this guide prints **“Not publicly stated”** rather than guessing.

These are the criteria we judged against, our own product included.

- **Simplicity.** One plan a manager can read in a minute beats a grid of tiers.
- **Suitable for a non-technical team.** Set it up without a developer.
- **Team sharing.** How many people can read the codes, and whether each signs in as themselves.
- **Pricing you can predict.** Per number beats per person, and a message allowance is where a cheap plan gets expensive.
- **Focused on receiving codes.** A tool built for texting customers back is a different product.
- **Ease of setup.** Minutes, not a project.
- **The type of number.** Some services refuse an internet-based number — often called VoIP — for security codes, and that fact decides more of these purchases than price.

## Five services, and ours, side by side

Ordered by the cheapest published way in, not by preference.

| Service | Starting price | Team access | Dedicated number | Inbound SMS | Outbound SMS | Best for |
| --- | --- | --- | --- | --- | --- | --- |
| Group2FA | $3.99/month | 3 invited members plus the subscriber; up to 20 only on the $5.99 or $15.99 plans | Yes | Yes | Forwarding to members only; by text where supported | Lowest monthly price, and numbers outside the US |
| MultiMFA | $5/month per number | 2 users on the entry plan | Yes | Yes | Not publicly stated | Testing the idea before you pay |
| Shared SMS Inbox (this site) | $49/month per phone number | Unlimited teammates, own logins | Yes, one | Yes | No | One price whatever the team size |
| Team SMS | $34.99/month for one number | Shared with the team; users: Not publicly stated | Yes | Yes | Not publicly stated | A real US mobile number on one plain plan |
| JoltSMS | $50/month per number | Up to 10 people, in three roles | Yes | Yes | Replies only, on an existing conversation | A real US mobile number with roles and history |
| Daito | $19/month plan plus $49/month per number | 3 users on the entry plan | Yes | Yes | Not publicly stated | A German number and hosting in the EU |

_Pricing and product information checked: September 2026, from each vendor’s own published pages. Prices change — check the vendor’s pricing page before you buy. Where a vendor does not publish a figure, this table says **“Not publicly stated”** rather than guessing._

## Group2FA

- **What it is.** Apps for iPhone, iPad and Android, plus a browser web app, giving a small group one shared number. Every member gets each code in the app or by push notification, and by text or WhatsApp where supported — the vendor publishes that “Outgoing SMS messages are available to select Country Codes” and does not say which.
- **Pricing.** $3.99 a month for an internet-based number, 3 invited members and 100 messages; $5.99 for 5 invited members and 250; $15.99 for a real US mobile number backed by a physical SIM, 15 invited members and 700. The allowance counts the incoming code plus every copy forwarded to a member — the vendor’s own example is 4 messages per code in a group of three — so 100 messages is nearer 25 codes unless forwarding is turned off. In-app messages and push notifications do not count. Numbers elsewhere are priced individually: United Kingdom $9.99, Netherlands $14.99, Australia $15.99, Israel $25.99.
- **What we like.** The cheapest published monthly price with a number included, the only choice of five country codes here, and the cheapest published route to a real SIM-backed US mobile number.
- **Things to consider.** The US plans cover 3, 5 or 15 invited members plus the subscriber, and every number outside the US covers 5. The $4.99 add-ons that raise a group to 20 attach only to the $5.99 and $15.99 plans, so the $3.99 plan’s 3 members cannot be increased — twenty members costs $20.96 or $20.98 a month. Messages are metered. Your number is exclusive to you, but the terms let Group2FA reassign it if it receives no code for three months in a row, with notice in the app and the offer of a replacement. Every tier below the top one, and every number outside the US, is internet-based. Trial length is **Not publicly stated**, as is whether a card is required and whether the app keeps a searchable history.
- **Best for.** A small group wanting the lowest monthly price, or a number in the Netherlands, Australia or Israel — its UK number only receives texts from GB senders.

## MultiMFA

- **What it is.** A dedicated number built only for verification codes, which land in a shared inbox and are forwarded to the people the owner has approved.
- **Pricing.** $5 a month for 2 users and 100 messages per number; $10 for 5 users and 500; $20 to $50 for 10 to 25 users and 1,000. Extra messages are $0.025 each.
- **What we like.** The way in is cheap and reversible: 14 days or 25 texts, whichever runs out first, with no credit card. Message text stays visible while the number exists, with optional erasure after 24 hours or 7 days.
- **Things to consider.** The number you can buy today is internet-based, and the vendor publishes the consequence: some platforms reject these numbers, some accept them but hold back the code, some deliver inconsistently — naming Microsoft and Amazon sign-in workflows, OpenAI and Discord. Its SIM-based alternative is a limited pilot and cannot be bought yet. Which countries it supplies is **Not publicly stated**, as is whether you can send or reply.
- **Best for.** A team wanting a fortnight to find out whether this works for its own accounts before paying.

## Shared SMS Inbox

- **What it is.** A company phone number whose incoming texts arrive in a web inbox. It receives and does nothing else.
- **Pricing.** $49/month per phone number, and that is the only plan. Teammates are unlimited and cost nothing extra. The account is free and asks for no card; you pay when you activate a number. There is no time-limited trial — the free part is the account, not the number.
- **What we like.** Unlimited teammates, each with their own login, so no password circulates. Access is granted per number and per person, and administrators see every number. History is kept, with each message’s text erased on a schedule — 72 hours by default — while the record that it arrived stays, next to a record of who gained or lost access and when messages were opened.
- **Things to consider.** Receive-only, so nobody can reply. The countries our numbers come from are **not yet published**. And we publish no guarantee that our numbers are real SIM-backed mobile numbers: if a service refuses internet numbers, JoltSMS, Team SMS, Group2FA’s $15.99 tier and Daito publish something we do not.
- **Best for.** A team wanting one number, unlimited people reading it, and an invoice that does not change as the team grows.

## Team SMS

- **What it is.** One plan sharing one number with your team, described as a real phone number connected to a physical SIM card and hosted in the US.
- **Pricing.** $34.99 a month for one number, and that is the only price on the site: no annual option, no tiers, no per-person charge.
- **What we like.** The number type is published in plain words — “a real phone number, connected to a physical SIM card, and hosted in the US” — the sentence a buyer with a fussy service is hunting for. Messages route on to Slack through Zapier.
- **Things to consider.** US numbers only, no trial published, and the terms state purchases are non-refundable. How many users are included is **Not publicly stated**, as is whether you can send or reply and how long messages are kept. The vendor publishes little beyond a homepage, a one-plan pricing page, and terms and a privacy policy both dated March 2024 — plus a developer documentation page whose contents do not render in the public page.
- **Best for.** A small team needing a real US mobile number on a single flat plan, and willing to buy on a short published record.

## JoltSMS

- **What it is.** A dedicated US number for verification codes, with a shared inbox, message history and three levels of access.
- **Pricing.** $50 a month per number, or $500 a year, described as two months free. No setup, activation or per-message fees, and team access is included up to 10 members per number.
- **What we like.** More published team detail than anything here: an Owner who controls billing, a Manager who can view messages and set up notifications, and a Viewer who can only read, all seeing the same inbox and history. Inbound messages are unlimited under a fair-use policy, the number is a real-SIM US mobile number on carrier hardware, and codes route on to Slack, Discord, Telegram, Microsoft Teams, email or your own systems.
- **Things to consider.** At $50 a month per number it carries the highest per-number price here, and several numbers add up. US numbers only, no choice of area code, ten members per number. No trial is published — **Not publicly stated** — and checkout charges immediately, with no partial refunds on cancellation and annual plans non-refundable from checkout. The number is leased rather than owned and cannot be moved to another provider. Replies are limited to an existing conversation, and the fair-use threshold is never published as a number.
- **Best for.** A team needing a real US mobile number, named roles, a message history and no message allowance to think about.

## Daito

- **What it is.** A business login-code manager — shared authenticator codes for company accounts — with an optional German number that drops SMS codes into the same shared inbox.
- **Pricing.** The entry plan is $19 a month, or $15.83 billed annually, for 3 users; larger plans run $49, $149 and $399 for 10, 50 and 150 users. No plan includes a number — those are $49 a month each on top — so receiving a text starts at $64.83 a month billed annually, or $68 billed monthly.
- **What we like.** A German +49 number published as not internet-based, which nothing else here offers outside the US, and hosting in the EU. There are two trials, 14 days on the plan and 7 days on the number, and codes can be forwarded into a Slack channel.
- **Things to consider.** The most expensive entry point here, and German numbers are the only country published today — the vendor says it is “currently using mobile phone numbers from Germany and plan to expand to other countries soon”. The inbox is documented as visible to everyone in the organisation, and whether that can be narrowed is **Not publicly stated**. The plan trial takes no card — “No credit card needed” — but the vendor publishes that the 7-day number trial does require payment details, “due to legal and regulatory reasons”. The record of who saw what is kept for 1 day on the entry plan, rising to 7, 30 and 90 days.
- **Best for.** A German or EU team wanting authenticator codes and SMS codes in one place, inside the EU.

## The customer-messaging inboxes are a different product

You will have found these too. They are good tools built for another job, and buying one to receive codes usually costs more and works less well.

Sakari, MessageDesk, Quo (formerly OpenPhone), Heymarket, JustCall, Textline, Text Request, Avochato, Salesmsg, Missive, Kixie, TextBetter, Trengo and Front are shared inboxes for talking to customers by text. Most charge for each person: published seat prices run from $14 a month at Missive to $49 at Heymarket, several set a minimum number of seats, and some add message credits on top. A few charge by volume instead — Sakari from $25 a month, Text Request from $59.99 — and Textline publishes no base price at all, only the add-ons: **Not publicly stated**. For five people who only need to read codes, per-person pricing multiplies a cost you did not need.

Two of them also publish that their numbers are a poor route for verification codes. Sakari does not recommend this kind of number for security codes and says it will not troubleshoot codes that fail to arrive. Quo publishes that its numbers cannot receive messages from short codes — the five and six-digit senders many codes come from. That does not make them bad products. It makes them the wrong shape for this job.

## Is it a real mobile number or an internet-based one?

The most practical issue in the comparison, and the one most buyers discover only after paying.

A phone number can be issued over the internet, or it can sit on a real SIM card in a mobile network. Both receive texts perfectly well, but the service at the other end can often tell which is which, and some refuse the internet kind for security codes — or accept the number and then never send a code to it.

- **Publishes a real SIM number.** JoltSMS publishes that its US numbers are real-SIM numbers on carrier hardware rather than internet phone lines. Team SMS publishes “a real phone number, connected to a physical SIM card, and hosted in the US”. Group2FA publishes a real US mobile number backed by a physical SIM, but only on its $15.99 tier. Daito publishes that its German number is “a real phone number connected to a physical SIM card which is hosted by us”, and not an internet number — the only non-US number here published that way.
- **Publishes an internet-based number.** MultiMFA publishes that the numbers it sells today are internet-based, and lists which platforms tend to reject them. Group2FA’s $3.99 and $5.99 tiers and its numbers outside the US are internet-based, and it publishes that this type works with most online services but not all — banks and social media platforms usually wanting a real one.
- **Does not publish either way.** Ours. We publish no guarantee that our numbers are real SIM-backed mobile numbers, so do not assume it. If a service has already refused you an internet number, buy from one of the four above.

> Nobody here guarantees a service will accept their number: JoltSMS publishes that it cannot promise any number will pass a platform’s checks, and MultiMFA that it does not guarantee delivery. Put the number on one real account and send yourself a test code before you rely on it.

## Which shared SMS inbox should you choose?

By requirement rather than by rank, because these products win on different things.

### What is the cheapest way to try a shared SMS inbox?

MultiMFA publishes the clearest free look: 14 days or 25 texts, whichever runs out first, with no credit card. Group2FA and Daito publish trials too, and for the lowest ongoing price Group2FA starts at $3.99 a month with a number included.

### Which one gives you a real mobile number rather than an internet-based one?

Four publish it outright. Group2FA’s $15.99 a month tier is the cheapest, Team SMS is $34.99 a month and JoltSMS is $50 a month — all United States numbers — and Daito publishes a German mobile number on a physical SIM, from $64.83 a month.

### Which is best for a team outside the United States?

Daito, if you want a German (+49) number and hosting in the EU. Group2FA if you want a choice: it publishes numbers for the United Kingdom at $9.99, the Netherlands at $14.99, Australia at $15.99 and Israel at $25.99 a month.

### Which keeps a message history your team can look back at?

JoltSMS publishes the same inbox and history for everyone with access. MultiMFA keeps message text visible while the number exists, with optional erasure after 24 hours or 7 days. Ours keeps a history too, with the text erased after 72 hours by default.

### Which one has no monthly message limit?

JoltSMS. It publishes unlimited inbound messages under a fair-use policy sized to normal verification volume — though the threshold is never published as a number, so ask what it is before you rely on it.

### Which has the simplest pricing?

Team SMS and ours are level here: one plan, one price, no charge per person. Team SMS is $34.99 a month for one number and ours is $49/month per phone number.

Daito publishes two trials, 14 days on the plan and 7 days on the number, but the number trial asks for payment details and turns into a paid one unless you cancel. Group2FA advertises a trial without publishing its length.

Our account is free and asks for no card, but the number is charged from the day you activate it — so we are not the cheapest way to look around.

Daito is the only non-US option that publishes it, in the same terms: “a real phone number connected to a physical SIM card which is hosted by us”. We publish nothing here, so all four beat us on this.

Group2FA also publishes that a UK number “can only receive SMS from other GB Country Code message senders”, so a code sent from a non-UK sender will not reach it.

JoltSMS and Team SMS publish US numbers only, and which countries MultiMFA supplies is **Not publicly stated**. Our own list is **not yet published**, so buy from a vendor that names theirs.

For Group2FA and Team SMS this is **Not publicly stated**, so ask before you buy. A long history is convenient, and it is also a list of login codes sitting in a browser.

The two cheapest options meter: MultiMFA allows 100, 500 or 1,000 messages a month per number and charges $0.025 for each extra, and Group2FA allows 100, 250 or 700 — but its allowance is consumed by the incoming code plus every forwarded copy, so 100 is about 25 codes for a three-person group.

Team SMS does not state how many users are included, where ours is unlimited; it publishes a real SIM-backed US mobile number, where we publish no guarantee.

## Where ours fits

If what you need is one number, a shared inbox and incoming texts only, ours is the plain version of that: $49/month per phone number, unlimited teammates with their own logins, access granted per person, and a history that erases the text of each message on a schedule. That describes a fit, not a verdict about which product is best.

Where a competitor fits better, buy the competitor. A service that refuses internet numbers, a number outside the United States, or a fortnight of testing first are all things somebody above publishes and we do not.

## Questions buyers ask about ours

### When do I have to pay?

You pay when you choose and activate your phone number. Creating an account, looking around and inviting colleagues costs nothing and asks for no payment details. Billing starts at the moment the number becomes yours, at ${PRICE.perMonth} for that number, and stops when you cancel it.

### Is this an inbound-only number?

Yes. Receiving text messages is all the number does, there is nothing to configure to keep it that way, and no teammate can text somebody by accident. If your team also needs to send messages — to customers, candidates or suppliers — this is not the right tool for that job.

### Can I cancel anytime?

Yes. There is no contract and no minimum term — you cancel from your account settings and the monthly charge stops. Before you do, move any company account that still uses the number across to a different one: a phone number you have given up should not be relied on to come back.
