We have a couple of iPhone 5 and 5S phones - GSM SIM -
Took a trip from Chicago over to Michigan, and up along the coast to Petoskey, Michigan via Traverse City and Saugatuck, etc - When we arrived I noticed that the phones had the 4G icon, so thought all was good for looking up places on Yelp, etc.
Well - NO -
there was NO DATA because we kept receiving the -
PDP Authentication Failed error message.
So basically, our phones were useless until we were in range of our B&B and their WiFi - or someplace where the PDP error was not appearing..
Looking up our vacation location on the Ting / T-Mobile Coverage Map -
this is what appears in the drop block.
Our iPhone 5S is not listed for LTE - but we still should have had some flavor of data - but all we had was the PDP Auth error -
REALLY BAD -
