I have been trying to connect to Vodafone in the UK using a PAYG SIM unsuccessfully. The client has a Vodafone mast in their burilding so we no there is no problem with coverage.
SIM's from 02 / Virgin Media (who use Vodafone) work fine but Vodafone ones connect but do not pass data and do not allow a speed test - shows a 'failed to connect to server' message.
Have tried all the options as given in the Teltonica list (https://www.teltonika.org/apn-list/
) and followed all other ideas from on the Crowd support to no avail.
Any ideas? I've also tried multiple Vodafone SIMS and two different RUTX11's...
