Out-of-the-box unlocked phones are well known in the UK, Europe and across Asia. Approximately 70-80% of phones are unlocked in Europe in Asia. High end unlocked phones typically sell for $ 600-$ 700 USD and it’s quite shocking that people will spend that much for a ‘quick fix’ so that they can use any networks SIM cards for cell phones in their mobile phone.

In North America, only 5% of the population owns an unlocked phone. The main reason behind this is due to North American carriers rewarding users to extend contracts by subsidizing prices on phones.

However, the real benefit is that it completely eliminates all international roaming fees!

How to unlock your phone

Another option is to contact the original network that provided you with the phone and SIM cards for cell phones. They can send you the phone’s PUK code which you can then enter into the phone to unlock it. The network may charge you for the PUK code and it all depends on how long you have been with the network and how much money you’ve spent on cells,messages etc.

Which mobile phones can be unlocked?

Virtually any GSM phone can be unlocked. A GSM phone is a device which can take SIM cards for cell phones from various mobile phone network providers. If you having problems getting your phone unlocked, then you can always contact the phone manufacturer’s service centre, even if the phone is out of warranty they should still help you out.

How to use your unlocked cell phone

After purchasing an unlock code and entering it into your phone, you will not eliminate the possibility of having to pay high international roaming fees. International Roaming fees accrue once you step on foreign soil. Your phone will automatically link with one of your network’s international roaming partners (ex. If you are British on T-mobile, travelling to Malaysia, as soon as you hit Malaysian soil, your phone will say Celcom Malaysia). Even if you receive a phone call and do not pick up, you will be charged more than $1.50 for your phone going to the Voice mail.

So how do we get rid of the international roaming fees? Simple! Buy a local SIM cards for cell phones before you leave home and you won’t have to worry about high international roaming charges when you arrive at your destination country.

Alternatively you could always buy a pre-paid SIM cards for cell phones when you arrive, but I guess buying before you leave home give you one less thing to worry about when you arrive at your country destination. Also you’ll be able to make calls the minute you step off the plane and while your waiting for your luggage at the carousel!
