....for a cellular trail cam that requires you to do so....which have you ended up using? I have the choice between AT&T and T-Mobile. I was looking at this place: https://www.eiotclub.com/fr/product...TY7cH2zJNh4fEXbkUYcnLM6IqotrAecBoCMv4QAvD_BwE and if legit it seems like it'd be the cheaper route. Maybe there are other similar or better options out there.
