A GrizzlySMS alternative with extra codes included

Why do people look for sites like GrizzlySMS?

People rarely leave GrizzlySMS over billing, because its model already charges only for received codes. They look for an alternative when a sign-up needs a second code, when a country they rely on runs dry, when a payment method fails, or when they have hit the support limit on refunds for bad numbers in one country.

A second provider with the same API is the cheapest insurance in this market. If both accept SMS-Activate-style requests, your tool can try one and fall back to the other without code changes beyond a base URL and a key.

Can one number receive more than one code?

GrizzlySMS's FAQ (checked October 24, 2026) says its numbers are one-time, usually receive one SMS, are issued for 20 minutes and support multiple codes only for Instagram, Dream11 and Zupee. If an app sends a second code because the first attempt failed, you normally need a new number.

On TempSMSVerify, any code the app sends during the up to 20 minutes the number is reserved appears in the same order at no extra cost, whatever the app. That is the most practical difference between the two services for sign-ups that ask you to retry.

How do refunds compare?

When no code arrives, both services return the money. GrizzlySMS says the balance is refunded within 20 minutes of purchase or when you press Cancel. On TempSMSVerify, the price is only frozen at purchase; it is released automatically when the number expires without an SMS, and the cancel button unlocks after about 2 minutes.

The difference is the edge case where a code arrives but the number turns out to be used or banned. GrizzlySMS refunds those if you send a screenshot within 20 minutes of purchase, may ask for a video, and caps retail buyers (web users or fewer than 100 activations a week) at refunds for 3 numbers per country. On TempSMSVerify, contact support with the order details and our refund policy at /refund-policy applies.

Can I move a GrizzlySMS integration to TempSMSVerify?

Yes, for the core flow. GrizzlySMS documents an SMS-Activate-compatible API at api.grizzlysms.com/stubs/handler_api.php, and TempSMSVerify serves the same protocol at https://tempsmsverify.com/api/stubs/handler_api.php. Change the base URL and api_key, then call getCountries and getServicesList to confirm ids before your first order.

GrizzlySMS-specific parameters such as providerIds, exceptProviderIds and phoneException, and its v2 and v3 price methods, have no equivalent here, so remove them or keep those calls on GrizzlySMS. If you prefer JSON, our REST v1 API at /api/v1 does the same job with normal HTTP status codes.

Is TempSMSVerify cheaper than GrizzlySMS?

There is no single answer, because both catalogs price each app and country by live stock and change during the day. Compare the exact app and country on both sites at the same moment; ours are listed on /temp-number-prices. We do not copy GrizzlySMS prices here because they would be wrong tomorrow.

Then compare what a successful verification really costs: whether a retry code needs a new number, the card fee (TempSMSVerify charges 10% on card top-ups and nothing on crypto) and the minimum top-up, which is $3 on GrizzlySMS and $5 on TempSMSVerify.

When is GrizzlySMS the better choice?

GrizzlySMS is the stronger fit if you want to start with $3, pay with an online wallet, use its site in one of ten languages, try its eSIM beta, connect an AI agent through its MCP server or filter numbers by provider through its API. Its catalog also lists separate US lines it labels as virtual, which helps if you choose by line type.

TempSMSVerify makes more sense when your apps often send a second code, when you want card payments through Stripe and refunds that need no screenshot for orders without an SMS, or when you want one balance that never expires across REST and the SMS-Activate endpoint.

Do the same usage rules apply?

Yes. Use numbers only to verify accounts you own, follow each app's terms and never use them for fraud, spam, impersonation or getting around bans or regional restrictions. Our acceptable use policy at /acceptable-use explains what is allowed.
