I posted this on the wrong forum on Thursday when I found this out and just realized it! So reposting here because 5G is only available on the newer phones and I meant to post here originally anyway 😊
TMobile has just released an update about their 5G and issues with SIM cards. They have found that customers whose SIM cards have the letters TM plus 4 numbers are not 5G compatible. The new compatible SIM cards have R15 on them and are compatible. If you have a non compatible SIM card and have a 5G phone, please reach out to TMobile for a new SIM card.
I found that I actually did need to replace my SIM card as it was one of the old ones, which I knew it was but everytime I called TMobile and asked they told me it was a good one. I went on Thursday and replaced my SIM with the new one and my phone has been working much better, switching between 5G and LTE without a problem.
Solved! Go to Solution.
The wife and I are having issues with our S20 including:
So far we have done the following:
What has temporarily fixed the issue is rebooting the phones. Here is another odd occurence that happened today:
We have full bar 5G cell strength. We have strong Wi-Fi and we have tried both cell service and Wi-Fi calling. Nothing fixes the issue permanently.
Any ideas from anyone?
This is a known issue increasingly more common. And it is a major fault. The phone is not fit for purpose. Samsung need to get this resolved. A flagship phone that cannot receive phone calls is simply ridiculous.
See the following threads. It is not carrier specific. It's a handset issue not a network provider issue.
You will find toggling flight mode on and off restores connectivity.
Harrass Samsung until it is resolved. The more people who report this issue directly and forcefully to Samsung the more likely it is a fix or even an acknowledgement of the issue will come. I suspect Samsung are trying to avoid a PR disater by not publicly acknowledging this fault.
i have the same issue with my S20 Ultra on tmobile...it's not actually a Samsung issue as much as tmobile exagerating their 5G network areas...I've commented on this repeatedly but here's a link to my last response to someone else with same issue and how to fix it:
hope this helps!
did switching to LTE help with your connection issues? Just wanted to follow up and see if you gave it a shot or not.
