Replacing landline with mobile number but keeping existing hand sets?

k6chris

This is probably a dumb question, but is it possible to get an adaptor that has a sim card in it, which can then plug into an existing IDECT house answer phone (replacing the cable from the land line)?  I am trying to find away of replacing a land line with a mobile sim, but keeping the traditional phones the house already has.   Hope that make sense??

Thanks!

GSM gateway? Used to be banned but possibly a gray area now? Can you get them in 3g? 2g has a limited life.

Some of the Huawei 4g mobile routers are supposed to let you plug in a telephone, sometimes for VoIP but I hear often just to use the SIM. If you found an older one with the right firmware it might work.

Seen https://www.ligo.co.uk/ligo-bluewave-hub suggested in past but don't really understand it.

Or give up and use a VoIP adaptor and route all calls over the internet with sip. Easier to get.
