Hello,
I have the S4 and for the past 2 weeks, I have been losing my data connection all together. I have tried rebooting the phone. Removing the sim card. Changed network mode from LTE to Global. Changing the Mobile virtual network operator type back and forth from SPN to IMSI. Turning mobile data off and on. Getting rid of the cashe for the messaging (was having issues sending and receiving MMS) It also will not connect even if I am connected to wifi. My signal strength right now is reading -101 dBm 39 asu.
What else can I do besides throw this phone on a roof?
Thanks in advance
