# A GrizzlySMS alternative with extra codes included

Source: https://tempsmsverify.com/compare/grizzlysms-alternative · Last updated: 2026-10-24

GrizzlySMS is a large one-time activation marketplace with a wide country list, an SMS-Activate-compatible API and an eSIM beta. Like TempSMSVerify, it charges only for received codes. The useful differences are smaller and more practical: how many codes one number can take, how refunds for bad numbers work, how you pay and which tools connect.

## What is a good GrizzlySMS alternative?

A good GrizzlySMS alternative should match its pay-on-delivery billing and work with the same API. TempSMSVerify charges only when the SMS arrives and refunds automatically otherwise, includes extra codes on any app while the number is active, offers 140+ countries and serves the SMS-Activate protocol GrizzlySMS clients already use.

## Verdict

Both services charge only for received codes and both speak the SMS-Activate protocol, so switching is low-risk. GrizzlySMS has a lower $3 minimum, more languages, an eSIM beta and an MCP server. TempSMSVerify includes extra codes for every app while the number is active and takes cards through Stripe. Keep both if stock matters to you.

## Steps

1. **Open an account.** Sign up at TempSMSVerify and add at least $5 using Card via Stripe (Visa, Mastercard, Amex, Apple Pay, Google Pay); Crypto (USDC or SOL on Solana).
2. **Check your key apps.** Compare stock for your usual app and country on /temp-number-prices and on GrizzlySMS at the same time.
3. **Test a retry.** Verify one of your own accounts and, if the app offers it, request a second code to see it arrive on the same order.
4. **Generate an API key.** After your first top-up, create a key in the API section of your dashboard and store it safely.
5. **Swap the base URL.** Replace api.grizzlysms.com with our handler_api URL and drop provider-specific parameters.
6. **Add a fallback.** Let your tool try one provider and fall back to the other when NO_NUMBERS comes back.

## 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.

| Task | GrizzlySMS (from its docs) | TempSMSVerify |
| --- | --- | --- |
| Base URL | api.grizzlysms.com/stubs/handler_api.php | https://tempsmsverify.com/api/stubs/handler_api.php |
| Buy a number | getNumber (with optional maxPrice, providerIds) | getNumber with service and country |
| Read the code | getStatus or getStatusV2 | getStatus, or GET /api/v1/orders/{id} |
| Change status | setStatus | setStatus 1, 3, 6 or 8 |
| Prices | getPrices, v2 and v3 | getPrices and getNumbersStatus |
| Active orders | List of active activations | GET /api/v1/orders |

## 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.

## FAQ

### Does GrizzlySMS charge if no code arrives?

No. GrizzlySMS's FAQ (checked October 24, 2026) says you pay only for received codes and that the balance is refunded within 20 minutes of purchase, or when you press Cancel, if no code arrives. TempSMSVerify uses the same principle: the price is frozen at purchase and released automatically if the number expires without an SMS.

### Can I get a second code on a GrizzlySMS number?

Only for some services. GrizzlySMS's FAQ says multiple codes are supported only for Instagram, Dream11 and Zupee, and that its numbers usually receive one SMS. On TempSMSVerify, any further code the app sends while the number is reserved, up to up to 20 minutes, is included at no extra cost for every app.

### Will my GrizzlySMS API client work with TempSMSVerify?

For the core activation flow, usually yes, because both services speak the SMS-Activate handler_api protocol, so your loop of getNumber, getStatus and setStatus stays the same. Replace api.grizzlysms.com/stubs/handler_api.php with https://tempsmsverify.com/api/stubs/handler_api.php, use your TempSMSVerify api_key, drop GrizzlySMS-only parameters such as providerIds, and confirm ids with getCountries and getServicesList.

### What is the minimum deposit on GrizzlySMS and TempSMSVerify?

GrizzlySMS's FAQ lists a $3 minimum deposit by bank card, online wallet or cryptocurrency. TempSMSVerify has a $5 minimum top-up with Card via Stripe (Visa, Mastercard, Amex, Apple Pay, Google Pay); Crypto (USDC or SOL on Solana); card top-ups carry a 10% processing fee and crypto has none. On both sites, unused balance stays in your account for the next order.

### What if a GrizzlySMS number was already used or banned?

GrizzlySMS says it refunds such numbers if you send support a screenshot within 20 minutes of purchase, may ask for a video, and limits retail buyers to refunds for 3 numbers per country. On TempSMSVerify, orders with no SMS are refunded automatically; for a problem after the code arrives, contact support with the order details.

### Does TempSMSVerify offer eSIMs like GrizzlySMS?

No. GrizzlySMS lists eSIM as a beta product. TempSMSVerify focuses on one-time SMS verification numbers in 140+ countries, reserved for up to 20 minutes. If you need mobile data or a long-term line, use an eSIM or rental provider, and keep TempSMSVerify for one-time codes on accounts you own.

### Can I use GrizzlySMS and TempSMSVerify together?

Yes. Because both accept SMS-Activate-style requests, a tool can try one provider and fall back to the other when it gets NO_NUMBERS. A TempSMSVerify balance never expires and is charged only when a code arrives, so keeping a small backup balance costs nothing while you wait for stock to change.
