Mine has come back alive now but only on one the networks with lowest reception so it is only transmitting very infrequently.

Globallink 520 LTE-M Connectivity for UK

Reprising the conversation since the change of community forums. Are there any advancement and/or solutions to SIM cards to be used in the Globallink 520 in the UK? My unit has been rendered unusable for a long time now. Potentially unresellable as well, at least in the UK. Thanks
