This app isn't in any of our charts yet.
BusySMS no longer asks for permission to make phone calls. It used to offer to look up a SIM's own number by dialling your carrier's "my number" code for you, which needed that permission. If your carrier doesn't tell the app your number, you now type it once and we prove it by texting a code and watching it arrive on that SIM. The app asks only to receive and read verification messages, on the SIMs you switch on.
Your own phone's verification texts, on the other devices you own.
BusySMS carries the verification messages your own phone receives across to the other devices and systems you own — a web dashboard, your own scripts, a browser extension on your computer. It is a cross-device transfer tool for your own messages. The phones are yours, the SIMs are yours, and nothing anyone else receives is ever in reach. It is not a shared or rented number pool. WHAT IT DOES • You install BusySMS on an Android phone you own and switch on the SIM(s) you want it to carry • Each number is confirmed by a quick SMS round-trip, so a number can only be added by whoever holds the SIM • From then on, verification messages arriving on those SIMs are carried across to your other devices • A visible notification shows whenever it is running, and you can stop it at any moment WHERE THEY ARRIVE • The BusySMS web dashboard, in your browser • Your own code, over a REST API — useful when the phone and the computer are not in the same room • A Chrome extension that puts the code into the box you are looking at • MCP, so an assistant working on your behalf can read them too WHAT IT DOES NOT DO • It does not carry your whole inbox — only verification-style messages, while a SIM is switched on • It does not send messages, place calls, or read your call log • It does not sell, share or profile anything it carries PRICING • $5 per active SIM per month • 7-day free trial, billed monthly, cancel any time • Switch a SIM off and it is no longer billed Works on Android, with a companion dashboard at busysms.net. Sign in on both with the same phone number. Use only phones and numbers you control. BusySMS is not for reading anybody else's messages.
