What is the cheapest LTE gateway or USB modem with voice support? - eviltoast

I have a goal is to setup home VOIP solution to keep my 2-4 SIM cards at home while travelling abroad. Getting data and SMS is easy, but I really can’t find any devices that actually support both voice and LTE.

Unfortunately all hardware I can find is either old 2G/3G GSM gateways o custom mods using “asterisk-chan-dongle” and all available dongles only support 2G / 3G hardware which is being discontinued in my area and no longer work reliable.

I would really appreciate any advice here. Thanks.

    I want LTE gateway for home to redirect calls to SIP when travelling and not worrying about losing them.

    I am digital nomad so have multiple sim cards that I need to maintain working and want to receive calls on, so just using VoIP number isn’t exactly good option.

      Now I get it. Could you unconditionally forward incoming calls on those SIMs to a voip DID and then sign into that service from abroad? You’d eliminate a lot of complexity and points of failure this way - your home setup is completely out of the loop.

        Yeah I know that call forwarding would be easier to setup, but unfortunately it’s not always work especially for outgoing calls and it’s exactly I wanted to research hardware solutions.

        Actually idea with iphone isn’t that bad. I just need to check if it’s possible to setup multiple iphones to receive sms and calls.

          Okay, it looks like this iphone feature only work if both phones on the same WiFi network and unlikely there is way to overcome it.

          So it’s typical Apple - implement some useful feature, but limit it to be completely useless for power users.
