Cudy P5 not working with the AT&T prepaid account
I Purchased a Cudy - 5G SA/NSA AX3000 Wi-Fi 6 CPE, Model: P5 and purchased the 50gb Prepaid data plan from AT&T.
I have gone through 3 SIM cards with no luck getting them activated to my account. The third SIM card was put in this morning and I had 4G Cellular service until the AT&T rep added the ICCID onto the account. Now I don't have cellular connectivity or access to the internet.
I put the SIM card into an iphone and could not connect to data either.
I put a Verizon SIM card into the router and it worked without an issue.
Any insight to what the issue could be? Do I have the right data plan? I'm not the only one using this router with AT&T so there seems to be something wrong with the setup...
