Frequently Asked Questions
How do I get started?
Sign up, add Credits, and choose your SMS Kit. Follow the activation steps to get started.
How many SMS Kits can I have?
As many as you want. There's no cap.
What's an SMS Kit?
An SMS Kit is your hosted mobile line for sending and receiving texts through WebSMS or our API. Every Kit runs on its own dedicated mobile connection, powered by an eSIM or a physical SIM. API access is available exclusively to Premium-level customers.
Can I receive texts from online services?
Yes. Your number can receive messages from any sender that can deliver to it. Keep in mind that some online services run their own verification and security checks. They may decide not to send messages to certain numbers.
How long can I keep my SMS Kit active?
When you activate an SMS Kit, you'll choose a prepaid service period from the available options. Your plan renews automatically as long as auto-renewal is enabled and you have enough Credits.
You can turn off auto-renewal anytime and keep using your Kit until the paid period ends. If you no longer need it, you can also delete it from your account at any time.
Where do I find my messages?
In your Inbox. Every incoming message shows up there.
Do I pay for incoming texts?
Nope. Receiving texts is free.
Has my number been used before?
Your number has never been assigned to another Proovl customer. However, mobile numbers can have a history. Operators may recycle them after a period of inactivity, so a number supplied as new may have been used years ago.
Your number stays yours while your service is active, and we never reassign it to another customer afterward.
Can I use a number for just one text?
Absolutely. If one message is all you need, that's totally fine.
The full SMS Kit price still applies. Your number is dedicated to you and doesn't go back into our inventory when it expires.
What if a text isn't coming through?
Messages received by your SMS Kit appear in your Inbox.
Some online services use their own security and anti-fraud checks. They may consider your IP address, account activity, device, location, or past usage and decide not to send a message. When that happens, the issue is on the sender's side, not with your SMS Kit.
Do I need any extra hardware?
Nope. We host everything for you. All you need is an account.
My country isn't listed. Can I still use the service?
Yes. You can choose an SMS Kit from any destination we currently offer.
Do you offer discounts?
We don't offer discounts on SMS Kits, but you can get discounts when buying Credits. Available offers are shown on the balance top-up page. We also occasionally send special discount codes by email.
Why is part of the phone number hidden before activation?
We partially mask phone numbers before activation to protect unused inventory. The full number appears in your account once your SMS Kit is ready. Some carriers require additional setup before the final number becomes available.
How long can a text be?
Message length depends on the characters you use. Emoji and some alphabets take up more space, so fewer characters fit into a single SMS. Longer texts may be split into multiple SMS segments.
Can I send and receive texts in other languages?
Yes. We support Unicode, so you can text in a wide range of languages and character sets.
Can I use an alphanumeric Sender ID?
No. Your outgoing messages always show your assigned mobile number as the Sender ID.
Can I send texts?
Yes. Sending is optional and requires identity verification (KYC) and approval before it can be enabled.
Can I send texts worldwide?
We support a wide range of mobile networks around the world. Availability depends on the destination and carrier.
Is there a sending limit?
Yes. You can send 1 outgoing message every 2 minutes.
Why might an outgoing text not be delivered?
A few things can get in the way:
the recipient's carrier
local messaging rules
spam filters
an invalid or unreachable number
blocking or opt-out settings
temporary network issues
Once a message leaves our platform, final delivery is up to the destination network.
Am I charged if an outgoing text isn't delivered?
You may still be charged even if a message isn't delivered. Some operators charge for processing a send attempt, regardless of the final delivery status.
Do you have an API?
Yes. Our API lets you manage your SMS Kits and phone numbers and receive incoming texts through signed callbacks. API access is available to all active accounts.
What kind of phone numbers do SMS Kits use?
SMS Kits work with real mobile numbers through dedicated eSIM or physical SIM connections.
How soon will my SMS Kit be ready?
Most SMS Kits are ready to go shortly after activation. Some numbers need extra setup on the carrier's side, which can take up to 24 hours.
Do I need ID or documents to activate an SMS Kit?
Some SMS Kits can be activated without ID or documents. Others have additional carrier or regulatory requirements. Any applicable requirements are shown before activation.
Can I swap my number for a different one?
No. Numbers can't be exchanged once they're activated. Need a different number? Just activate a new SMS Kit.
Which countries are SMS Kits available for?
Yes. Our list of destinations changes based on current inventory and carrier availability. You'll always find the latest options on our website.
Can I restore a deleted SMS Kit?
No. Once your SMS Kit is deleted, it cannot be restored or recovered. Its message history may also be permanently deleted.
