Hello I have new X1 Carbon gen 13.
I am having issues with connection on Tmobile simcard + esim. I have no issues with other providers O2, Vodafone, Airalo etc. Only with Tmobile.
Simcard works normally in other devices such as ipad, iphone etc.
I am located in Czech republic.

I have RM520NGLAAR03A03M4G Driver version 1.3.0.15

Any chance there is newer version of the driver?
I have done already 5x clear installations of windows and no change.

Thank you

Dear @Jura_JuraCZ
Do you contact with T-Mobile to check if there are some limitation in PC?
Or try to configure APN.

Hello thank you very much for your reply.
We doublechecked with Lenovo premier support and everything is OK.
APN is configured properly. I thought maybe some new version of driver could help but if there is none, then I will have to use other provider such as Vodafone/O2

Dear @Jura_JuraCZ
If install PC directly, we don’t have corresponding driver, it need Lenovo driver.
