Hello, my mobile phone is Huawei C5700 Telecom Edition. What does it mean to show R on the 3G signal? Now the phone and SMS functions are gone!

Dear users, hello, I'm glad to serve you. According to the information you provided, the analysis is as follows:

This R symbol stands for data roaming. You are currently using the mobile data function when roaming (some mobile phones may be inaccurate due to firmware problems, but they will be displayed when not roaming, but it will not affect your normal use). Another possibility is that your mobile phone has a system failure. I suggest you go to the after-sales service of your mobile phone, and ask the after-sales engineer to help you detect and sort out your favorite mobile phone, so as to find out the reasons and solve them in time and put them into normal use.

At present, Anhui Telecom Network Hall has launched relevant mobile phone preferential activities. If you need to buy a machine, please log in to Anhui Telecom Online Shopping Mall to buy the latest mobile phone. If you need to check the account and pay the phone bill, please log in to the online business hall of Anhui Telecom and send it to 2 yuan after 100.

I hope my answer can bring you some help and be adopted by you. Thank you.
