    Does anyone have an idea why Verizon chose to use an MCC of 311 for their LTE network rather than 310?

    Good question. Actually, I'm still not clear why the USA has two MCC's (310 and 311). Usually countries have just one MCC. Maybe bigger countries, like the US, need to have 2 :confused:

    List of mobile network codes in the United States - Wikipedia, the free encyclopedia

    Most US operators seem to use 310. Not sure why Verizon took 311 for LTE. Maybe just to have it clearly separated from their CDMA network, would be my guess.

    thank you for the feedback. I was doing some reasearch and found that the US is allocated 6 unique MCCs, 310-315. Majority of the articles out there also indicate that we are running out of MNC numbers on the 310 MCC and so more and more carriers are spilling into the 311 MCC.

    One working theory I read about for the Verizon LTE network using MCC=310 is that they are projecting to run out of IMSI's on that MCC/MNC combination. Something to do with high projected growth in machine to machine devices, etc...
