Solved: 4g issue

Gu · ‎19-11-2019

Hello
I have dual sim Xiaomi Mi A2 phone with O2 business and Lebara SIM card. I can get very good 4g network with Lebara SIM card but I never had any 4g network with O2 business SIM card. I have contacted O2 multiple time bad they have sent all APN SETTINGS.
I have also got replacement simcard to correct this issue but no success.

Please advice.
Thanks

Only one sim card slot supports 4G Data, as per this from Xiaomi Website

"When using two SIM cards, one will support 4G
while the other will not."

iPhone 16 Pro Max - o2 and Spusu

Have you enabled 4g on both SIM slots or swapped the sims around ?

That's what I figured hence the question about swapping sims around.
