Cellular phone lines for anywhere, and backup when lines fail
Get a normal phone line over a 4G SIM for cottages, construction sites and kiosks, or keep your office phone system working when the internet or copper lines go down.
Cellular Phone Lines & Backup
Copper landlines are disappearing and some locations never had them. A fixed cellular terminal turns a SIM card into a standard phone line that works with any phone.
For offices, cellular gateways give the phone system automatic backup lines, so customers can still reach you during an outage.
