SIM cards compatibility in the US


Below we have gathered useful information for customers that have issues with getting a correct SIM card from US operators.


1. SIM card size

Our devices use a mini-SIM (2FF) SIM card size. Obtain SIM kit with the correct SIM size from your operator.


2. Choosing a plan

Our device requires calls/texts services enabled, data is not required. Depending on a carrier, it can be M2M or IoT plan or a normal plan just like for a mobile phone.


3. IMEI number

If your cellular operator requires IMEI number for a SIM card activation, you can check the IMEI on SMSEage device in web-GUI > menu Settings > tab Sysinfo.
