I’m looking to use the T-Mobile DIGITS app over a VPN, preferably using WireGuard.

It appears that t-mobile.com and DIGITS are unreachable via Mullvad and Proton but, bizarrely, work completely fine via ExpressVPN.

Sadly, ExpressVPN does not support WireGuard.

Does anyone know of a VPN provider, other than ExpressVPN that is not blocked by T-Mobile?
