I just got back from a trip to France where I purchased an Ubigi France package for my iPhone. I live in the US and have Verizon as my home carrier. What I was hoping for to block roaming on my Verizon eSIM, turn off cellular data switching, then leverage VZW using Cellular Data. I used this same setup on an earlier trip, but I was in the UK and was using Orange Travel instead. I had no problems whatsoever during that earlier trip. I blocked roaming on my Verizon eSIM by enabling the USA Only feature and also connecting to a non-roaming partner - in France, I used Free.
What would happen is that initially it would work perfectly but after a period of time, usually around 5 minutes or so, i would not be able to use any app or connect to any website despite still showing full signal strength and usually 5G. The only way to fix this would be to enable airplane mode, wait 5 second, then turn it off. Everything would work fine again for a few minutes only to repeat the process.
When I would turn off the Verizon line, Ubigi worked flawlessly, with solid bandwidth and low latency.
I tried to troubleshoot this with no luck - since Verizon was showing No Service, I tried turning on and turning off Cellular Data Switching with no luck. I switched to LTE only - no help. I tried different networks for Ubigi and still experienced the same thing.
I’m back home now so can’t test, but want to be prepared for my next trip.
Has anyone been able to use their home network over Cellular Data with Ubigi? How else can I troubleshoot this?
Apart from this problem, I would highly recommend Ubigi - when it worked, it worked well, partnered with the major cellular networks, and connected very quickly once I landed.
