Tip & How-To about Cell Phones

Mobile Phone Repair Guy's Top Tips!


According to a recent survey, more than half of all travellers now travel with a mobile phone. And with the added convenience a mobile phone can bring to your trip, this is hardly surprising.

To ensure that you’ll be able to use your phone abroad you’ll first need to enable international roaming with your mobile phone operator. If your mobile phone is on a contract this won’t be a problem, but some pay-as-you-go mobile plans don’t allow this feature.

It’s a good idea to check what you’ll be charged for using your mobile abroad, for calls and texts. Some operators will also charge you to receive calls whilst you are out of your own country as well, so bills can add up without a call even being made!


If you are planning a long stay in any particular country, it may work out cheaper to buy a local sim card at your destination. Some operators don’t allow you to switch sim cards, and will lock your phone - your operator will be able to give you more information on this. Alternatively, some independent phone retailers will be able to unlock handsets for you.

Your mobile phone will pick up the strongest network while you are abroad. As this won’t necessarily be the cheapest network you may want to do some local research and look into changing your phone’s settings to pick up the cheapest network.


Make sure that your phone details are registered with your mobile operator before you travel. If your phone is stolen, contact your customer service department and give them your mobile number and IMEI/serial number so that your operator can suspend your number. Report your loss to the local police and get written confirmation with a crime number for your insurance claim.


Ensure that the battery has been charged. Take the battery in and out of the phone again. Try another battery in the phone if you have access to one. If this does not work it may be liquid damaged or have a software problem.


If you drop your mobile phone in liquid never try switch it on immedeatly. You need to dry it out first as the short circuit from trying to switch on a wet mobile phone could do more damage then the liquid damage itself


-You’ll need a tri-band phone if you’re travelling to the US or Canada
-Your international access number may vary between countries
-Save important numbers in your mobile phone before you travel
-Take a travel adapter with you to make sure you can charge your phone
-Research the cheapest local networks on arrival
-Make sure you know how much you’re paying to make and receive calls and texts
-Keep a record of your mobile phone’s IMEI/serial number and phone number, in case of theft
-Mobile phones can be a top target for petty theft, so make sure you don’t flash it around too much!

Why is my Nokia phone asking for a PUK code?

The PUK code is an 8-digit code from your service provider used to change a disabled Personal Identification Number (PIN) code. The PUK code will be requested when an incorrect PIN is entered multiple times. Please contact your service provider for this PUK code.

If you have already contacted your service provider and the PUK code provided did not work, it will be necessary to obtain a new Subscriber Identity Module (SIM) Card from your service provider. The PUK code is used to protect your phone from unauthorized access and if multiple attempts at entering the PUK code occur, the SIM card will become inactive for your protection.


Please try the following troubleshooting tips:

Ensure that your phone is powered on and that there is sufficient signal strength. When you are at the start screen or in a call, the strength of the radio signal is indicated by the signal indicators on the left side of your phone''''s display. These indicators move up as the strength of the signal increases and down as the signal decreases.
If there is a headset attached to the phone, it will not ring. You should be able to hear the ringing through the headset. Detach the headset and retest the phone to determine if that resolves the issue.

Check to see if the phone is in the "Silent" profile. If the phone is in the "Silent profile", change the "Silent" profile to the "Normal" profile and retest. To change your profile, please refer to your user guide.

Ensure that a ring tone has been enabled and the volume is not too low. (Please follow the instructions in your user guide.)
If your phone goes straight to voice mail without ringing and your phone is powered on and you have sufficient signal strength, your service provider may need to reset your voicemail services.
If your phone still will not ring, please submit your phone to repair so they may try to resolve the issue for you.


Ensure that the battery has been charged. Please refer to your user guide for charging instructions. Remove the battery and replace.

Check if you have the correct battery for your phone. If you do not have the correct battery, please return to your point of purchase to obtain the correct battery for your phone or purchase the appropriate battery for your phone.

If you have access to another battery and charger of the same type as yours, try substituting them to determine if the issue is with the phone, battery or charger. Your phone may also have a software problem or be liquid damage in which case you have to send it or drop it in for repair.

Subscribe -The text message and e-mail features are supported by the service provider. To use these features, you have to subscribe to the service.

Please contact your service provider for more information on the availability of these services in your area. The service provider will also need to assist you in storing a message center number.
Load Settings - Multimedia Messaging Service (MMS), Short Messaging Service (SMS), and E-mail settings may be available on our website. Please visit our settings area.

If you have subscribed to this service and loaded your settings and are unable to send messages, please contact your service provider


Before you even start trouble shooting ask yourself whether your phone may be barred from the network if it is stolen or the account holder did not pay their bill....If this is not the case then ensure that your phone is powered on. Hold the power button down for a full 3 seconds. (The power button is often located on the top of your phone. Please refer to your user guide for the location of the power button for your specific phone).
Confirm that your service is active. If you are unsure, contact your service provider.

Check that you have sufficient network signal strength. When you are at the start screen or in a call, the strength of the radio signal is indicated by the signal indicators on the left side of your phone's display. These indicators move up as the strength of the signal increases and down as the signal decreases. To increase your phone's signal strength, try moving your phone slightly, or move towards a window if you're calling from inside a building.

If you are still unable to place a call, please contact your service provider. If they are unable to assist you, please submit your phone so it may be inspected for repair.

If you have forgotten your security code, or the security code is not working on a Nokia phone, please try the following:

The factory default security code is 12345. The default lock code is 1234. If you entered a wrong code three or more consecutive times, the phone may switch to a "sleep mode" and not accept any entries for the next 15 minutes. Please power the phone off, then back on, and let it sit idle or untouched for 15 minutes, then try again. If this does not work we can flash the phone for you but you will loose the data. You have to have proof of ownership for us to do this for you.


This is very good sign of liquid damage


This is a example of where your phone has been liquid damaged.
