I have an S8, it's been working fine since I bought it months ago. Today it says invalid sim and contact sprint to unlock my phone. If I restart, it will work for about 3 minutes and then revert back to these two messages with no service. I've been through ##72786# and again only got about 3 minutes of a working phone before it reverted back to those same two messages. How do I fix this?
I have an IPhone 5S through Boost, and I am experiencing the exact same problem. For a while, I've noticed my phone only falsely connects to wifi but is really using cellular data. Now add on this service issue and it's becoming the last straw. It is infuriating. I'm missing calls and texts directly related to work and I am seriously considering ditching Apple and Boost for Google FI. I like Boost and don't want to drop such a large amount of money but if this doesn't clear up by today I'm going to have to.
I was driving to meet a friend yesterday, and the lost service so lost GPS. Luckily the directions were loaded on the phone and I could pull over and read them and navigate to the location.
I've reset the network, did a soft reset of the phone, power cycled it multiple times, turned off LTE data, nothing is working.
Please fix this stat, or I really have to abandon my service with Boost.
A lot of people don't know this as Samsung did a bad job explaining But...
You have, or should, have a program called "smart switch" on your phone.
If you open it, press transfer to external device, backup, it will save everything on your phone to your sd card.
You can then factory reset. After phone Re boots, go to smart switch, external, RESTORE.
About 5 minutes and it will be like you never touched your phone.
And we all know it's always a good idea to regularly back up devices anyway whether we are haveng issues or not....
