So, I already have a help ticket in but looking at the app reviews on the play store I’ve noticed that I am not the only one with this problem so I thought I would document it here as well. My mom recently upgraded to the galaxy s8 and the service at my uncle’s house was abominable so we requested a CDMA sim card which we received. After the fact I installed it and activated it assuming all was good. She gets a message at random times every day saying to restart her phone or to activate her phone. So this is what we have done in the ticket so far (and this is reasonable to try all of this. Note that I am getting a carrier signal and it does work sometimes but it also will kick me off periodically and I have to find a wifi network in range of the cellular network to reactivate which is dangerous since if my car broke down around the time this happened I would have no phone communication ability.
Reset the state (get it to search for other types of network operators again)
Provide applications installed… this one is a bit annoying since I’m a tech geek so I install things on my parents phone to troubleshoot such as ampere and open signal but they told me to uninstall open signal (surprise that didn’t work) then I updated the prl and profile in settings (still didn’t work)
Since the above did not work he also suggested doing the “VOIP” refresh (note that I have been able to call out using wifi since this trouble began so voice over internet protocol is not the problem, did it anyway) the code is ##8647## and the dial button if you want to continue following along.
At this point the service desk did an internal change and asked to update my data profile (settings > system updates > update profile) I always do this in conjunction with a prl update so I did the prl update, restarted, and then did the profile update and restarted again.
Now the old great solving method of nuking everything, they asked me to do a custom factory reset using ##786# instead of the regular way through settings. After backing up her messages and phone log (the only 2 things that don’t automatically back up) I did the reset which did not help
Currently there is a response saying to contact Samsung for hardware replacement. Since the phone is connecting to Sprint towers with no trouble I am completely sure that this is not a hardware problem so I tell them this and they are going to send me another sim card I guess.
This is a long of my full interaction with the help ticket crew at this point and they are very nice and have some good ideas to check, at this point I’m pretty sure that the sim card just isn’t whitelisted in the republic system, any other ideas to try? Attached is the picture of my diagnostic screen (ignore the million wifi warnings as I am at a place with a limited wifi connection)
Note the “Network Operator” problem
