I have the same issue as others have reported here:
There is a conflict it seems with EE unlimited data sims bought via a well known UK company (also on amazon) and the rutx50. Till end of January 2024 everything was working fine. Now neither of my two EE sims connect via this router no matter how you play with the settings or how far you rollback firmwares. The router works fine with other sims and the EE sims work fine in other routers but since end of January there is some conflict with the router and the sims.
You can sporadically get things working sometimes just by scatter gunning lots of things which may even be just sim switching from sim 1 to sim 2 but then any changes, even changing the external antennae, will take you back to square one. On the latest firmware RUTX_R_00.07.06.3 i cant get things working at all any more however.
errors i get include
“Limited service is displayed when the modem is not registered on the network and is camping on an emergency cell”
“Mobile network rejection was recently detected”
“All available APNs were tried, unable to make connection to operator, try to enter custom APN or adjust mobile settings to make connection”
And Network type shows as 3G (WCDMA).
both auto apn and custom apn fail
does anyone have any solutions or has teltonika acknowledged this issue?
