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.

Some helpful tips from our US customers
- Use a delay between SMS texts (can be set in menu Settings > Application) to prevent blocking by spam filters.
- Send messages from each modem to the other modems every 1 hour (this creates an artificial "chat" traffic) so the line is not cold.
- Encourage the recipients to reply as one-way text will get a number blocked more quickly.
- Consider using MMS instead of SMS.
