Yes, you can absolutely use Voyced on your smartphone without WiFi.
As long as you have a working mobile data connection (3G, 4G, or 5G), you can connect your SoftPhone app to our Hosted IPPBX and use your Voyced number just like you would on a desk phone or PC.
What do you need?
-
A SoftPhone app (like Groundwire, Zoiper, or Linphone)
-
A mobile data connection
-
Your Voyced SIP account details
Once set up, you can make and receive calls using your VoIP number, even when you’re away from WiFi, ideal for remote work, travel, or full mobile flexibility.
1. Using your regular mobile provider’s data
You can use your existing SIM and mobile plan, but be sure to check:
-
Is VoIP traffic allowed? Some mobile networks may restrict or degrade SIP-based calls
-
Do you have enough data? A VoIP call typically uses 0.5–1 MB per minute
-
What about roaming?
-
Roaming with your mobile SIM can be very expensive, especially outside the EU
-
Some providers block VoIP while roaming
-
Check your provider’s rates and rules before using data abroad
-
2. Use a Voyced Roaming eSIM
If your smartphone supports eSIM, Voyced offers a Roaming eSIM solution that works in almost 200 countries.
-
Keeps your SoftPhone connected on the go
-
Avoids roaming surprises from your regular SIM
-
Ideal for travel, remote work, or global businesses
-
Runs alongside your existing SIM, no need to remove it

3. Use a Voyced OfficeSIM (Physical SIM)

Voyced also offers the OfficeSIM, a physical SIM card that works in many countries and is fully compatible with VoIP usage.
-
Works in phones that don’t support eSIM
-
Offers reliable mobile data and voice where supported
-
A great solution if you want an all-in-one mobile setup for VoIP, data, and travel
Contact us to find out if OfficeSIM is available in your region and fits your needs.
