  1. I purchased a Reolink Go but didn’t realize that I had to use a prepaid SIM card so it would not connect. I opened a ticket but didn’t get a response until the day I returned it. I will order another one and try again with a prepaid SIM card. I suggest that it is very clear on the Amazon site that you MUST use a prepaid SIM card.
