My call won't connect: what should I check?
- Always dial the full international number, and make sure it's valid and working
- Start with "00", followed by the country code and the destination number
- For example, to call the UK from abroad, dial 0044 followed by the number
- Check your SIM is inserted and active
- Make sure you're using the correct call type
- If one call doesn't go through, try another number, or check whether the number is premium-rate
Does my registered number need to match my SIM?
- Yes. The phone number registered in the app should match the SIM card in your handset
- This helps verify your identity and improves connection reliability
Which call type should I use?
- Use Local access when your SIM has inclusive minutes, or when you want to route the call via your network carrier
- Use Wi-Fi when you're on a Pay as You Go SIM with no credit, or when you want to call over an internet connection
- Use Data when you have sufficient mobile data on your SIM or when you're abroad and only have inclusive data roaming
Can I call businesses and premium-rate numbers?
- The app does not support premium-rate numbers
- If you call a business with a premium-registered number, the call will not connect
