It will work fine with FirstNet, AT&T and T-Mobile.
The original target market for the Transit Mini was for FirstNet Band 14 and T-Mobile Band 71 customers which is why we don’t have the Verizon logo on the MAX Transit Mini page on our site or datasheet.
When we realized the radio actually covered the Verizon bands as well we looked into this but it turns out the LTE radio vendor had to make some small change to the module in order to get it certified on the Verizon network.
The original TAC or IMEI’s are apparently now blocked from being used on the Verizon network, even with a pre-activated SIM.
This “newer” version of the module is now Verizon certified and hence we have also moved ahead with the Verizon certification of the MAX Transit Mini and it should be completed in the next few weeks.
Thanks
