Device support
The device support list below shows the compatibility of devices in combination with Telavox Mobile, and does not reflect or list up the features of devices. All Models/operating systems which are not mentioned in this list, do not support Telavox Mobile at the moment.
This is a constantly evolving list and will be updated consequently. If you have any doubts or questions about a specific device, please reach out to our sales or support team.
Note
Please make sure that the device itself actually supports the technical feature. (VoLTE, 5G, VoWiFi, etc.)
For example: If a brand in combination with Telavox Mobile supports VoLTE or 5G, this does not mean that this device has VoLTE or 5G as a technical feature available.
A tip for devices supporting multi-SIM cards:
On some devices, SIM1 is technically “better” (supports higher-end connectivity), while SIM2 may be restricted, so we advise you to use SIM1/Primary when testing or installing Telavox Mobile.
A2P SMS
What is A2P?
A2P SMS are Application to Person SMS messages. Various businesses/services send SMS to their customers (e.g. 2FA, forgot password, mobile number validation, etc). These SMS messages are usually sent from shortcode numbers (8801, 8820, 7200 and so on). There is a complex landscape of SMS aggregators between the business/service and Telavox and although A2P largely works, there are still some services that still need to be routed correctly.
A2P Status
Since we are a new mobile operator, these applications or SMS aggregators often have to make adjustments on their end to correctly deliver these to us. It is very difficult to determine which application reaches us through which route, but we are in contact with various SMS aggregators to resolve this.
This is a continuous ongoing improvement process that every new mobile operator has to go through until all SMS aggregators have been set-up correctly. The majority of the services are already functional however we are working hard to get the remaining ones up and running.

Mobile network information
Why is VoLTE important?
VoLTE means that your calls are using the 4G network (and not 2G or 3G). Due to the 3G network that has been shutdown by operators in Belgium and the low voice quality that you get from 2G network, VoLTE is the most important requirement.
Difference between calls over 4G/3G/2G:
- Better sound quality during calls:
- 4G: HD voice, much richer, closer to face-to-face conversation
- 3G: clear and more natural
- 2G: narrow, robotic, basic comprehensibility
- Faster call setup : From the moment you press “call” until the callee phone rings:
- 4G (VoLTE) : +- 1 to 2 seconds
- 3G (UMTS) : +- 3 to 4 seconds
- 2G (GSM) : +- 5 to 7 seconds
- Only with VoLTE you can call and use mobile data at the same time.
Make sure to check the Device Support list for our VoLTE support.
