2. Install the eSIM on your phone

NB: These processes vary with phone type, so please check the manufacturer’s instructions or Telecom26 Guide at https://t26.ch/go

2. How do I make sure my Telecom26 eSIM is used for mobile data?

After installing your Telecom26 eSIM, set it as the preferred eSIM for mobile data:

2. Under Cellular Plans, select Telecom26 eSIM
3. Tap Mobile Data and set Telecom26 eSIM as the preferred option

⚠️ If you skip this step, your device may continue using another SIM, leading to connectivity issues.

3. Why is the eSIM option not appearing on my iPhone?

This could be due to the following reasons:

1. iPhone Model Compatibility: Not all iPhones support eSIM. Check if your device is compatible
2. iOS Version: Ensure your iPhone is updated to the latest iOS version
3. Carrier Lock: Some iPhones are locked to a specific carrier and may not allow eSIM activation from other providers. Contact your carrier to confirm
