Step 1: After going through the Activate page successfully, check your email inbox for an email with the subject “Finish activating your Fonus SIM!“. Click on the one-time activation link in that email and enter the 19-digit ICCID number that is printed on your SIM card. Click “Activate” and make sure that your activation is successful.
Step 2: Insert the Fonus SIM card into your phone. Please disable or remove any other SIMs in your phone (if any).
Step 3: Go to Settings > Connections > Mobile networks > Access Point Names (see image).
APN page location may vary depending on the device. If you’re unable to find it at the above location, you can try searching for “APN” or “Access Point Names” within the Settings of your phone.
