Hi,

We’re having difficulty with some IoT modules not having any cellular connectivity. Output listed below. Any thoughts as to what is causing this? Being used in the UK if that’s relevant.

Jonathan,

A WP7601 only supports LTE bands 4 and 13 which makes it a US only module, it has no bands in common with the UK. You need to use a WP7607 unit.
