Frequently asked questions

What carriers are supported?
The selected board supports all LTE CAT-1 carriers and has support for 2G networks. We do not recommend using a (usually cheaper) board that supports only 2G/3G as those networks are getting phased out fast.
How long does it take to put everything together?
If you're comfortable with electronics and a bit of code, it should be less than an hour.
Where can I get support with self-assembly?
Visit the GitHub discussions and submit a question there.
