I am using Zorin OS 6 LTS, which I believe is technically Ubuntu 12.04 LTS.
Anyway, I was using an older 3G Modem from U.S. Cellular, and it worked perfectly with an easy setup (following this guide) but now they wanted me to upgrade to the Huawei UML397 4G LTE USB Broadband Modem.
I was okay with this, since 4G LTE should be faster (what is the difference between 4G and 4G LTE anyway?) I expected a setup as easy as the last, and it showed up under the list of available adapters.
But I got to the step where I select my provider (U.S. Cellular), and it wasn't listed! I tried to enter it in, but then it asked for more information that it didn't with the last adapter! It asked me for an APN, and when I asked U.S. Cellular for it, they asked "what's an APN?". Is this a generic number, or one specific to my account/adapter? I couldn't find any info on my APN number online, except for ones for phones.
What should I do?
I also tested this on my regular Ubuntu 12.04 LTS computer, and got the same result!
