What information does the electrical signal need to send?

Hello, first of all, thank you for your concern and support for China Telecom. According to your description, the service code varies from place to place. You can edit 1000 1 and send it to 1000 1, and then follow the SMS prompts to open it. You can also log in to the online business hall or the handheld business hall to open it.

The reply is for reference only. For details, please consult 10000 or visit Anhui Telecom's online business hall ah.189.cn. Anhui Telecom's online business hall is now launching iFree card, with zero monthly rent and zero threshold, free local calls for electric signals in the province, and the traffic is not clear. No package, no contract, no minimum consumption, no purchase restriction. Please visit Anhui Telecom's online business hall for details.

I hope my answer will help you and be adopted by you!
