Hello All,   I am struggling to bring up our MX68CW-WW's cellular uplink. Followed this doc for initial setup: https://documentation.meraki.com/MX/MX_Installation_Guides/MX67%2F%2FMX68_Installation_Guide   The device successfully registering in the Dashboard, when WAN1 port used as an Internet uplink. The LTE carrier is Telcomcel. The SIM card, which I am testing is removed from a different LTE device, where the SIM card was working perfectly, meaning the SIM card is active, no PIN required and has data. When it is relocated to the MX, the cellular upling status stuck in the Connenting phase.   Already verified: 1. APN Settings: tested with the deaults, does not work. Official docu from carrier: https://telkomcel.tl/p/internet-settings 2. There is no need to register IMEI of the device to use the carrier.   Does anybody faced similar issue? Any ideas what can be wrong?   Best, Janos   ... View more
