Using your phone abroad
This page is for help regarding roaming with your main Mozillion SIM or mobile plan. For help with Mozillion Travel eSIMs please visit here.
Mozillion plans include EU roaming across 41 destinations at no extra cost. This means you can use your plan’s data, calls, and texts while in these countries, including calling and texting back to the UK, without incurring extra charges.
When roaming, you can use:
- Up to 25% of your monthly data allowance on 3GB –100GB plans
- Up to 50% of your allowance on 1GB plans
- Up to 25GB of your allowance on 500GB and unlimited plans
Before you travel, make sure Data Roaming is enabled in your phone’s settings.
At present, you cannot use your Mozillion plan outside the EU or the UK, but new add-on services for international usage and calling will be available soon.

Before travelling, make sure Data Roaming is enabled in your phone’s mobile network settings, otherwise you won’t be able to use data roaming in eligible countries.

What is the difference between roaming and international calls?
Calling, texting, and using data outside of the UK in an eligible roaming destination is called roaming.
If you are in the UK or abroad and you are calling someone who is in another country from you, you are using international calls.
With Mozillion plans, you cannot make international calls from the UK or when abroad, but you can use your minutes, texts and permitted data allowance when you are in the EU eligible countries to get online and to call or text UK and local numbers for the country you are in, subject to our fair usage policy.
I am roaming currently and can’t make calls.
If you are unable to make or receive calls when roaming, it may be that the network you are roaming on doesn’t support VoLTE (4G) and WiFi Calling – see below for how to disable this feature so you can make and receive calls.
You may also need to change the mobile network that you’re roaming on using your phone’s settings. Please also ensure there is mobile coverage for the area that you are in.
I am roaming currently and can’t use data.
If you are unable to use data, try the following:
+ Ensure Data Roaming is enabled in your phone’s network settings.
+ Try manually selecting a different network in your phone’s network settings as not all networks have 4G or 5G coverage in all areas – for example, in Spain, some areas have better data coverage with Orange and some have better coverage on Movistar.
+ Check your data allowance to ensure you still have data available. You can purchase an additional data add-on from your Mozillion Dashboard if required.
Is VoLTE and WiFi Calling supported when roaming?
Mozillion supports VoLTE and Wi-Fi Calling, but not all networks in other countries offer these features yet. If you are roaming in a country where these services are unavailable and cannot make calls, you may need to disable VoLTE and Wi-Fi Calling in your device settings.
If you are unable to do this on your device, please contact us at [email protected], as we may be able to assist.
Roaming Fair usage policy
Our plans are priced based on reasonable assumptions of average usage considering comparable statistics from comparable service providers in the UK.
In case abnormal usage is detected, Mozillion reserves the right to suspend the availability of the bundle and/or to increase the price of any bundle in case of abusive, fraudulent, unreasonable, or abnormal usage. Such usage may include, but is not limited to, usage of bundles in permanent roaming (or with abnormally high roaming compared to national usage), abnormally high usage compared to industry standards, use of unauthorised equipment (including but not limited to “SIM boxes”, modems, and Wi Fi routers).
