Can I get a landline number that rings on my smartphone?
Yes. Port or get a DID number from any VoIP provider (VoIP.ms, Telnyx, Vonage Business, Twilio), then install Groundwire on iOS or Android. Groundwire registers against your SIP account and rings via push even when the app is backgrounded. One-time $9.99 — no subscription.
How do I get a local phone number in another country without a SIM card?
A DID number is a real, dialable phone number assigned to you by a VoIP provider in the target country. When someone dials it, the call travels over the internet to whatever SIP client you have registered — including Groundwire on your phone. From the caller's perspective it looks and behaves exactly like a local number. From your side, it rings like any other call, over Wi-Fi or LTE, wherever you are in the world.
