Hello, can an expert helping me. I have a sm-G998U1 s21 ultra I paid via Rakuten site.
My concern is that I am not able to get 5G signal, only LTE, knowing that my operator is FREE with 5G in France. My SIM card has no problem because when I install it on an other mobile phone I receive the 5G.
Questions to the expert:
- Is this s21 ultra model compatible with 5G European bands and if yes, how can I customize my phone to receive 5G?
- Taking into account that this model is an US phone, do you think it's possible that I change the firmware via ODIN by replacing the current version SMG998U1 (US) by a SMG998B (European) and will this solve my 5G problem?
Or this is impossible even with different firmware because it is due to the mobile hardware, the antenna is different on US models.
Thank you for your help.
