Thanks for your reply. I placed my phone is safe mode and nothing improved, It is still doing the same thing. This issue only occurs when I am at work in the 6114 zip code around 106th and Burt in Omaha. It shows I have 4 bars of signal but the 4G symbol only has the green up arrow and not the orange down arrow when this is happening. Text messages are saying failed but in most cases do send, but no internet available.
