Has anyone had success with using a SmartNet-provided AT&T SIM card in the Emlid RS2+?
I am trying to rearrange my equipment to improve my workflow and moved my SmartNet SIM from my data collector to my RS2+ base so that I can take advantage of NTRIP Castor and increase my range. However, I can’t get the “Use mobile data” switch to turn on. I used the APN that SmartNet requires (m2m005125.attz) but still no luck. I don’t think I’m missing something on my end with the Emlid Flow settings, much less the Emlid Reach hardware that should be compatible with AT&T.
I don’t have another SIM that I know would work in the RS2+. That’s kind of the problem. Very few cell networks will work with that modem for this purpose. Some work with the modem but not for an internet-only device. Others want more than I’m interested in paying for more data than I need so I haven’t bothered to give them a full trial.
According to the report, it looks like this SIM card either isn’t defined by receiver, or there’s PIN secure on it.
Please double-check that the SIM card fits tightly to the chip and the receiver determines it. Then, please share the screenshot from the Mobile data tab. If it requires authentication, you need to input credentials in this tab:
Network operator name is empty in the modem log, so I still assume it’s related to PIN secure somehow. So, you can also contact the provider to find out if there are any authentication requirements from their side.
There’s one idea what can be the reason for inability to activate mobile data.
SmartNet is a virtual network carrier that uses AT&T physical network stations. In its turn, AT&T can provide SIM cards with a standalone data-only plan. And we’re aware that this plan may not be supported by Reach modem. Hence, AT&T has to mimic a hybrid data/voice plan instead of standalone data plan to make SIM cards operational with Reach.
I’d suggest you to recheck it with the network carrier. Most likely, SmartNet isn’t aware of this because they’re a virtual operator. If so, you can ask them to clarify this point from AT&T or try to contact them directly. Perhaps, the second way be of more help if SmartNet isn’t responsive.
