Hi
I'm completely out of ideas how to fix this problem. I've searched all over the internet, but can't fix it. I've contacted the mobile carrier, they don't know. The phone manufacturer is poor with communication.
My Location: Melbourne, Australia
Phone: Umidigi S5 Pro
Operating System: Android 10
Mobile Phone Carrier: Amaysim (Optus Network)
Phone works perfectly in my home. I can make & receive calls, watch videos, download games. Everything is perfect. So, at least I know the phone can work & perform all the functions.
But, when I go outside my home base, the signal drops out completely "NO SIM DETECTED". I cannot even make & receive calls. This happens all the time. Eventually, maybe after 10 minutes (making no changes to the settings), the SIM is finally detected. But, it might easily drop out. It's totally unreliable.
To see if the problem is just poor network connection, I put the same SIM Card into two other phones (Oppo AX5 and Samsung J5108) in the same outdoor locations. Both phones easily connect to the mobile network immediately. I can make/receive calls, watch videos, connect to internet, etc. No drop outs. 100% reliability.
So, to summarise:
1) SIM card works in the Umidigi Phone at home without problems. 100% reliability.
2) SIM card does not work reliably in the Umidigi Phone outside the home base.
3) SIM card works in the Oppo phone & Samsung phone outside home base. 100% reliability.
So, it seems, the Umidigi Phone is having trouble connecting to the Mobile Network .. BUT ONLY outside my home base.
Is there some setting that needs to be adjusted? Maybe, someone has experienced the same issues with their phones or can someone with tech experience please provide possible settings that need to be adjusted?
The phone obviously can connect to the network perfectly at home. What could be causing it to not connect outside the home?
Thank you.
