Samsung i939d Telecom cannot send information.

Hello, first of all, thank you for your support to China Telecom.

According to your description, please try to change your card to another telecom mobile phone and see if you can send a message. If not, it's the card. Please change your card in the business hall with your ID card. If it can be sent, there may be something wrong with the mobile phone. It is recommended to take the purchase invoice to Samsung for after-sales service and let the staff check it for you.

Anhui Telecom will serve you wholeheartedly, and I hope my answer can be adopted by you.

Telecom broadband speed-up is free, 4M to 8M, 12M, 8M to 20M, 20M to 50M. You can go to the nearest telecom business hall or call 10000 to speed up for free. Please visit Anhui Telecom's online business hall for details.

If you have any questions, please consult the staff of Anhui Telecom's online business hall. Wish you a happy life!
