I have been having as of late problems with my iPhone XR. It has been very inconsistent in LTE performance. At the same location I can get good speeds (40 MB/Sec) to poor speeds (1 MB/sec). But others I consistently get very poor LTE speeds ( about .04 MB/sec ). Where I consistently get poor speeds is at the local Chick Filet, where I am unable to use the app when doing curbside pickup. Only once I have been able to use the app, because I happen to be close to their WIFI signal. I also had instances where I can't receive phone calls (they go to voicemail) nor can I send or receive SMS text messages. I have done a network reset on my phone several times. This is getting old and reseting the phone does not help at all. Is there a reliability issue with the XR and Verizon Wireless? I also find it interesting that I am experiencing these issues in conjunction with Verizon's 5G rollout.
I finding it to be too expensive to replace my phone for a new phone at this point. Would like some idea whether there are other iPhone models that have better and more consistent performance on the Verizon Wireless network. I am not interested in getting the iPhone 12. Costs too much.
