Pricing, Live Availability, Countries, and Services
How pricing works
On GlowSMS, open the catalog, choose a country and service, then see current stock and price before you pay.
That is the point of the catalog. You match one service, not a generic starting price. Offers change, so the catalog is the current source.
GrizzlySMS also changes offers. Its API documents a maxPrice feature, which can cap the price in an automated order.
Coverage
GlowSMS covers 180+ countries and 500+ services. You can check live stock for the country and service you need.
A United States number still depends on the service and current stock. The same is true for other countries. Broad coverage does not mean every service is in stock at every moment.
What GlowSMS gives you
- 180+ countries and 500+ services
- A live catalog for stock and pricing
- Country and service selection before you buy
What to check before you order
- Current stock and price for your service
- Whether a 20-minute activation is enough
- The offer details on the catalog page

The catalog shows what is available when you visit.
SMS Receiving Workflow: From Number Selection to Verification
On GlowSMS, add balance, choose a service and country, pick a current offer, and read the SMS in the dashboard. The number is temporary. It is for one verification task, not long-term phone access.
- Open the service catalog and select the platform.
- Choose a country with a current offer.
- Check the displayed price and stock.
- Place the temporary activation.
- Enter the number on the service you are verifying.
- Watch the GlowSMS dashboard for the code.
- Submit the code to finish verification.
The order stays open for up to 20 minutes. Resends from the same service can appear on that order if the first message is late or the service asks for another code.
Do not treat a temporary number as a permanent phone. Follow the terms of the service you are verifying.
Activation Duration, Resends, Refunds, and Support
Activation time
A GlowSMS temporary activation stays active for up to 20 minutes. Resends can arrive while the order is active.
You get one clear window for the task, without paying for long-term number rental.
If no SMS arrives
If no code arrives within 20 minutes, you can cancel an eligible order. The charge returns to your GlowSMS balance. This is a balance return, not a cash refund to the original payment method.
Read the current refund policy if you need the exact rules.
GrizzlySMS publishes its own refund and support rules. Read those before you order if failed activations matter to your workflow.
Before you use either platform, check the activation timer, resend rule, how to cancel, and where a refund goes.
API Capabilities, Integrations, and Automation
GlowSMS API
GlowSMS has a public REST API for SMS verification. You can buy a number, receive the OTP, and manage the order. The website and API share the same balance.
The documented flow is: list services, check offers, select an offer, poll for the code, then complete or cancel the order. An idempotency header helps prevent a duplicate charge if a request is retried.
Read the official docs for authentication, country codes, order states, rate limits, and errors.
GrizzlySMS API and maxPrice
GrizzlySMS has an API. Its docs include a maxPrice feature, which can skip offers above a set price.
That can help if your main need is a hard price cap. If you want a live catalog, 180+ country coverage, and a website you can try before you integrate, use GlowSMS.

Ease of Use
Most verification tasks are short. GlowSMS keeps the path to add balance, select a service, receive SMS, and finish.

GrizzlySMS may be easier if you already have an account there. Its maxPrice API can help if you need a strict budget in code.
