I recently got this MAX Transit Mini. I first tried it with my T-Mobile data prepaid sim. It is a 5G account and it worked but not 5G speeds. That was expected.
Then I swapped the sim to my Verizon prepaid data sim. It worked but was very slow compared to my WiFi hotspot 8800L. I usually get 40-60 Mbps in the hotspot downloads. In the Transit I only got 4-8 Mbps download speeds.
I left the Verizon sim in for a day. Then it quit working. No internet. Would not connect to Verizon. I tried rebooting and no change.
I took the Verizon sim out and put it back into the WiFi 8800L. It took a while but it is now working again. Getting 40-60 Mbps download again.
What could be the problem? The WiFi 8800L has no external antenna on it.
