Frequently Asked Questions
Everything you need to know about Altphone.cc. If you can't find what you're looking for, our support team is ready to help.
SMS OTP Numbers
SMS OTP numbers are temporary and rotate among global providers. If a number has already been used, simply wait 5 minutes. After this period without receiving messages, the number will expire automatically. Once expired, the provider processes the refund; this can take an additional 15 minutes (a total of 20 minutes from purchase) for the balance to be automatically reflected back in your account.
If you don't receive the SMS code within 5 minutes, you can manually cancel it to receive the balance back instantly. If you choose to do nothing, the number will expire at 5 minutes and the balance will be automatically returned to your account about 15 minutes after expiration (20 minutes total), provided no SMS message was received.
Usually, you have a 20-minute window to receive your verification code. Once the first SMS is received, you can receive additional messages from the same platform during that time at no extra cost.
No, our numbers are optimized exclusively for receiving text messages (SMS) for verification and OTP. They do not support voice calls.
eSIM & Data
An eSIM is a digital SIM card that allows you to activate a data plan without having to use a physical SIM. When purchasing from Altphone.cc, you will receive an instant QR code in your dashboard that you can scan with your phone's camera to activate it.
Yes. This is mandatory. Even if you are inside the destination country, you must enable 'Data Roaming' in your phone's cellular settings for the eSIM. This is because most travel eSIMs use international roaming agreements to provide you with the best local coverage.
Yes, you can scan the QR code and install the eSIM anywhere with an internet connection. However, your data service will only start working once you arrive at your destination country and the phone connects to the local supported network.
Privacy & Identity
KYC stands for 'Know Your Customer.' It is a standard process used by many companies to verify the identity of their clients by requesting personal documents like IDs, passports, or proof of address.
We believe privacy is a fundamental human right. Our mission is to provide secure, private access to global connectivity without requiring you to share sensitive personal information. By being No-KYC, we ensure that your identity remains yours alone while you use our eSIM and SMS services.

Yes, the current minimum deposit is $2 USD for balance recharges, which allows you to buy multiple OTP numbers or affordable data plans.
