Hi…i had a problem and i could observe that the modem will endeavor to associate again and again, here and there through 3G, some of the time by means of LTE, and will consistently stall out on “Getting an IP Address”. In the long run it will bomb sufficient occasions that it will change to another SIM (on the off chance that you have one) or hard fizzle and reset the modem, attempting again with a similar SIM.
