I don’t have this issue on my WAH7706.
1. What’s status
on your monitor? Does it show any error message?
2. What’s firmware
version of your device?
3. You can
check if your sim card supports below bands.
Multi-mode Multi-band design supports LTE B1/3/7/8/20/28/38
(B40 option), 3G B1/B8 (DC-HSPA+), 2G B3/8
