In my experience my prepaid coverage has not been in same as those with contract coverage.
A few years ago I was using T-mobile because my data connection was always slow or non-existent. I never felt like I was getting consistent 4G service and speed with my T-mobile prepaid service.
Around 2014 I switched to sprint prepaid, and bought a new phone that was specifically for the Sprint prepaid network. While using WiFi my phone always has an excellent internet connection.
Recently I took a trip to the beach and my data signal dropped completely. I could not receive any data and my phone was displaying messages about not having coverage. However, my sister-in-law could. She was streaming Pandora through bluetooth speakers while on the beach. She has a Sprint contract family plan. This has happened to me many times before, where I cannot receive data while other sprint customers can. It appears to me that Sprint gives priority to certain plans. I was wondering if this is normal or are certain Sprint plans / customers treated differently.
That's a great question. If you are experiencing connectivity issues, I recommend reaching out to your carrier for troubleshooting. Now to answer your question, there are a lot of stipulations that go into determining why and when a customer can access the tower. These include the number of people on the tower, what they are doing, and availability to the tower in the area you were at for vacation. On a postpaid plan, the type of plan doesn't determine priority. However, the plan does determine how much data a person can use in a bill cycle before deprioritization.
