4G Solar security camera internet connection
The camera is 4G America module. America frequency LTE B2/B4/B12 is compatible. Yet the camera does not connect to the internet service. I bought a SIM card from T-Mobile in Puerto Rico.The camera is...

@angranz Your problem is probably due to one of two things.
You need to put the SIM for the camera into another device, let it provision, and then enabled roaming (the roaming part is concerning, right from the get-go, when I looked at the specs). After that, follow the below to set the APN.
For a decent 4G APN, you can use an older T-Mobile APN example, like this one: Conexiones y red | APN and data settings (t-mobile.com)
The other potential problem is that the camera supports (4G): B2 B4 B5 B12 B13 B25 B26.
T-Mobile uses (in the US): B2, B4, B5, B12, B25, B41, B66 (higher freq. B4, basically), and B71
My guess is that the reason the manufacturer is saying you need to enable roaming, is that it can fall outside their supported bands, in a given area/towers. For example, if your strong tower-signal nearby is primarily B66, OR if the radio in the camera supports limited frequencies on those bands, it will fail to connect, hence them wanting you to enable roaming (to use limited TMO roaming data on that SIM/plan).
Honestly, I’d just return this camera if it were me, and get one that’s more solidly supported, from a manufacturer with a solid presence in the US, not because I’m opposed to CH-direct stuff (as an engineer I have a lot of one-off stuff like this around), but because if you have an issue, beyond something simple like fixing the APN, finding decent support will be VERY tricky (you might be able to find an English support site for discussion around this manuf. devices, looking around, maybe).
I’d also check the band/frequency crossover, of any future or replacements.
