How do I find the serial number on my mobile phone?
Switch on your phone. Dial *#06# using your keypad. The 15-digit code represents your serial number.
What’s the difference between PIN and PUK numbers?
Your PIN (Personal Identification Number) is important to protect your phone, and you usually enter your PIN when switching on your phone. If you enter the incorrect number three times in succession, your phone will be blocked and you will need your Pin Unlocking Key (PUK) to unblock it. Your PUK is part of the information that comes with your SIM card. Keep your PUK in a safe place!
Why is there a ‘no service’ message?
You might be receiving the ‘no service’ message because there is no SIM installed or it has been installed incorrectly. Remove the SIM and make sure it is clean. Reinsert it correctly.
Check that your service has not been canceled by your service provider.
Check that your phone is not in Flight mode.
If you are still experiencing problems, contact your service provider.
Why am I using so much data?
If you are unable to connect to a Wi-Fi zone regularly, and you need to keep a close eye on data usage, it’s a good idea to set a limit on your data usage. Services like WhatsApp use very little data, but downloading and streaming can soon use it up. Apps that run in the background can also use up data, for example, checking for emails or Facebook notifications. Set a limit on your data usage or turn it off now and again by using the Settings>Data>On/Off button on your phone.
How do I change the ringtone on my phone?
Mobile phones usually come with a number of standard ringtones, but you can personalise your phone by downloading ringtones of your choice from certain websites. Some phones will also allow you to allocate a different ringtone depending on the caller.
