5sim alternatives when 20 minutes isn’t long enough

What 5sim’s 20-minute window means

A 5sim number is yours for one activation, 10 to 20 minutes, and then it is gone. A code that arrives after that, a second app, or a sign-in a week later each need a new number, and it will usually be a different one from the number your account knows. For a throwaway sign-up that is fine. For an account you will open again, it is the reason to look elsewhere.

5sim is built for the short job. It covers about 180 countries, says prices start at $0.008 a number, refunds automatically when no text arrives, and publishes a price list with a success rate for each supplier. Its site also has an AI assistant that answers questions and can pick and buy a number for you. The rates are worth reading before you buy: on November 13, 2026, the cheapest US WhatsApp offer (0.85) showed a rate of 0, while one at 1.9231 showed 44.74%.

Your money sits in a balance you top up. 5sim shows any payment fee and conversion rate when you pay, and says refunds of the balance itself are handled on application within 30 business days, minus payment fees.

Five alternatives to 5sim

Prices as each site showed them on November 13, 2026. SMSPool shows no currency symbol on its prices; its deposit box is in US dollars.

1. SMSPool

   US Google/Gmail 0.48 to 0.85 per order

   Per-code pricing like 5sim, with numbers that stay longer

   SMSPool works much like 5sim, an order per code from a balance, in 150+ countries, but its numbers stay longer. Most suppliers’ numbers remain for up to 24 hours, and US numbers from its Foxtrot pool usually last 3 to 5 days, so a late code or a resend still has somewhere to go. Resends are capped at 25. It also rents numbers by the month.

   The catch: SMSPool says the 3 to 5 days is usual, not guaranteed. Monthly rental prices aren’t published, and WhatsApp can’t be ordered at the moment.

2. VirtualSMS

   Rentals from $0.25/day, for 1, 3, 7 or 30 days

   Short rentals in many countries, paid in crypto

   VirtualSMS sells both: single codes from $0.05 (US from $0.20) and rentals by the day in 145+ countries, which it calls dedicated. It says its numbers are real carrier SIMs, not VoIP, refunds automatically if no code arrives, and has an MCP server for Claude, Cursor and Codex.

   The catch: No card: cryptocurrency or SBP Russian bank payments only. The longest rental is 30 days.

3. 1001SMS

   Shown after you pick a service

   A rental from 12 hours, paid by card or Apple Pay

   1001SMS has 20-minute numbers charged only when the code arrives, much like 5sim, plus rentals from 12 hours to 12 months in 18 countries. A rental keeps the same number when you renew it, and one that has received nothing can be cancelled within 120 minutes for a full refund. Visa, Mastercard, Apple Pay, Google Pay, Alipay and crypto are accepted.

   The catch: Payments go into a USD balance, and rentals cover 18 countries against 5sim’s 180.

4. VerifyWith

   $3.99 for 1 day, $34.99 for 1 year

   A US number for any app that you keep a day or longer

   One day costs $3.99 and covers the code that arrives late, the resend and the second app, because every text from any sender reaches the number while you have it. It is a non-VoIP US number, and you can extend it to a week, a month or a year. There is no balance to top up and none to claim back.

   Head to head: VerifyWith vs 5sim.

   The catch: US only, receive-only. At 5sim’s US Google price of 0.3846, $3.99 buys about ten activations, so for one code we are not the fit.

5. TextVerified

   Google rental $1.40 for 1 day, $1.80 for 7 days (US)

   A US number for one app, rented by the day

   TextVerified rents a US number for a named service for 1 day to 1 year: Google from $1.40 a day, Telegram from $2.80. If you still want single codes, they are $0.75 for Google or Telegram, and it can deliver codes by voice call for $2.50.

   The catch: US only, one service per rental as its pages describe it, paid from credits you buy first.

Which one to pick after 5sim

If the code came and the account will never ask again, stay with 5sim. If the code came too late, or you keep retrying, SMSPool’s longer-lived numbers are the smallest change. If the account will text you again, pick a rental by country: in the US, TextVerified for one app or VerifyWith for several; elsewhere, 1001SMS or VirtualSMS.

SMSPool, 1001SMS, TextVerified and 5sim all ask you to load a balance or credits first; we don’t. To see whether a rental beats a handful of codes for you, try the per-code vs rental calculator.

Questions people ask

Can I keep a 5sim number longer than 20 minutes?

No. 5sim’s FAQ says its numbers can be used for 10 to 20 minutes and that longer periods are currently unavailable.

Does 5sim refund you if no SMS arrives?

Yes, automatically, according to its home page. Getting the balance itself back is different: 5sim handles that on application, within 30 business days, minus payment-system fees.

What do the success rates on 5sim mean?

They are 5sim’s own figures for each supplier of a number. On November 13, 2026, the cheapest US WhatsApp offer showed a rate of 0 and a pricier one showed 44.74%, so the lowest price is not always the likeliest to deliver.

Which 5sim alternatives work with an AI agent?

VirtualSMS, 1001SMS and VerifyWith each have an MCP server that an AI client can use to get a number and read the code. 5sim has its own AI assistant inside its site, which can buy a number for you.
