A question that I am constantly getting from students that travel around the world is “How do I unlock my phone?”. To some of you this may not make much sense, but essentially what the person is asking is how can I use my mobile phone around the world when I travel!
Most of the world is on a GSM network, which means that all you need to do is have a service provider for the country you are visiting, and you can make local calls and save lots of $$. For example, when I travel to the USA I take my T-Mobile Sim card with me and swap the sim cards around so I dont get hit by roaming rates!
Most providers lock the phones they give you to their network and in the UK (and I believe the USA) they have to provide you with your phones unlock code if you request it. Obviously, some take longer than others and they make you jump through hoops to get it.
But all is not lost, there are other options. The first one is to check that you phone is actually locked and the best way to do this is to ask one of your friends who is on another network if you can try their sim in your phone. If it works, your phone is unlocked, however if it asks for a code – it is locked.
If it is locked, there are numerous companies who can unlock it and your best bet is to simply google it:
phone unlocking – Google Search
Hope this helps you all
