Hi,
I previously had a UK EE e-sim in my S22 Ultra and since then I have switched networks to Vodafone UK (normal sim) but I am having a lot of issues with the signal.
Both my boy's phones (Sony and Xiaomi) work so much better on the same network and same location.
I noticed that the carrier service on the phone shows as EVR rather than VOD.
How do I change the service provider version without resetting the phone and is there a Vodafone UK specific firmware available?

Hello,
I bought phone from second hand it was vodofone uk. I have EE UK contract and I want use EE. Phone unlocked EE sim card is working. Problem is that I can't get EE Wifi calling service, because you upgrade to EE firmware. I need wifi calling because at my place signal is very poor. Phone firmware are vodofane Uk so I can't get EE wifi calling service. I tried to change firmware to EE UK, but phone always restarts. Is anything else I should do?
Can you recommend what I should do?
Thanks a lot
you need to flash the latest evr s6 firmware as this has the wifi calling feature built in

I'm using the BTU firmware and the second sim is stuck on 2g for data even though my second sim provider doesnt even have any 2g networks connectivity.
I read that thailand firmware lets you use 4g for calls and then 3g for data, but I'm concerned that if its using thailand modem settings for the UK as thailand providers may be using different wavelengths for their networks compared to the UK. Will my phone know that I'm in the UK and use the right modem settings, or will using thailand firmware force it to use thailand modem settings at all times?
I've been using the oneplus 7 pro fine for the past two weeks in Singapore and Hong Kong on local carrier sim.
Returned to Japan today and noticed I couldn't get cellular data after setting correct APN. Have tried switching to 2g/3g but no luck. The Docomo sim works fine with 4g signal when i put it back on my oneplus 6.
Any ideas?
Model was bought from oneplus US online. Model GM1917
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 SM-G998U1 (US) by a SM-G998B (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.
Hello, exactly same story with rakuten and SM-G998U1 s21 ultra
No way to get 5G working in France (with Free mobile).
I contacted Samsung Customer service. They told me the product was for American market, so don't expect it to work outside the USA.
The seller says it is compatible but in fact it is not.
I talked with the seller and they tried to explain me that it was 5G even if it is written LTE in the connection icon...
I also tried the tool ForceLTE to restrict to use only 5G (and no LTE) and I never get connected. I show them the screenshot and they realised there was a real problem.
Hello,
I have the same problem in Spain. All work fine, but It can't connect using 5G...
Were you able to fix the problem by installing some firmware or ROM?
Hi, I have yhe following issue and I need your thoughts please.
I have a Telus plan, canadian with US roaming option.
I am traveling in US alot. I have a Note 20 Ultra U1 from Samsung USA. When in US I can only register on Tmobile. Won't let me on ATT or Verizon.
With same sim card in Note20 Ultra "W" variant, canadian one, it wil register on all 3 major networks in US. No issues with the sim, I guess.
My provider said nothing to do with them, Samsung told me the same.
I reseted all network setings my APN is ok. VOLTE on. Only getting acces to Tmobile.
Any ideea how I can fix this ?
No ideas ? Might be the CSC ? Would XAC work ? Mine is XAA and also cannot get 5G in Canada with Telus on this device.
