I acquired a AT&T activated SIM card from one of the 3rd party subscribers and installed it in the router, it was great for 6-7 days. Download speeds averaged 30-35mb consistently throughout that first week. Then suddenly my internet went to literally .01mb. Of course did all the resets/reboots on the router with no fix. Contacted my internet provider and they sent me a new SIM. Put it in and everything was great again, 24hrs later internet slowed again to .01mb.
Does this sound like a router issue or a issue with my SIM card? Any suggestions is much appreciated as I don’t know much about mobile routers. I acquired the sim from nomad internet and is suppose to be unlimited data with no data caps or throttling but to me it acts just like I’ve been throttled.
I forgot to answer your other question above, I have set up 7 devices to connect to the router but generally there is only 2-3 connected at the same time.
AT&T is severely cracking down on unlimited data plans resold by unathorized resellers. This is typically done via increasingly aggressive IMEI sweeps to check that the IMEI of the device that the plan was activated on matches the IMEI of the current device. So, if Nomad or whoever you're using is reselling unlimted plans using phone or tablet IMEIs to activate the SIMs they are providing you with (or other data devices besides the LBR20) it would explain perfectly well why your service worked fine for a short time until they ran the IMEI check against the current network attached device. This is why I never recommend using resellers; the amount of transparency about what you're actually being sold on the backend is almost always zilch. Feel free to DM me if you have any further questions about these types of things. Hopefully your reseller is able to get you on a plan which will work for your LBR20.
The sweep can happen with people with plans and sims purchased directly through AT&T. It happend to me. They did it twice. Every 30 days like clock work.
