Frequently asked questions — A1
Our system currently indexes 18 numbers belonging to the A1 network in Bulgaria. The count reflects numbers that have recently received SMS or been validated.
No, TempSMSOnline is a receive‑only service. You can read all incoming SMS for any A1 number, but you cannot reply to messages, send outbound texts, or make phone calls.
Success rates vary. While A1 numbers are technically capable of receiving OTPs, popular apps often flag and block publicly shared virtual numbers. If one number fails, try another from the 18 available.
Go to the number’s dedicated page and use the community reporting tool. You can label the A1 number as spam, safe, or business. Your report helps other users avoid unwanted calls.
You remain anonymous because no registration is needed. However, the A1 inboxes themselves are transparent — every visitor sees the same messages, so never share private information.
Yes, A1 may allow customers to port their numbers to other networks. Our classification is based on original carrier assignment; a ported number might still appear under A1 in our system.
We monitor the 18 numbers continuously. Inactive or expired numbers are removed daily, and newly available A1 numbers are added as soon as they appear in public directories.
