Using Your iPhone Overseas
No one smiles wider when you go on holiday than your mobile phone provider. Journey abroad and they'll increase call costs and can charge up to £1 a minute for receiving calls too.
With an unlocked iPhone, you can remain with your existing network without any change to your existing service, plus, use a sim card from any other supplier, just when necessary.
ELIMINATE ROAMING FEES: Roaming charges can drastically increase your mobile phone bill every month. These roaming charges are based on either your current cell phone contract or the limits of service areas that your provider offers. Unlocking your iPhone can eliminate roaming fees by allowing you to change the SIM to lower priced networks or local networks when traveling.
SAVE WITH LOCAL RATES: An unlocked iPhone allows you to take advantage of cheaper rates from rival networks as well the ability to use local service providers whilst abroad. This will drastically cut down on your tariffs for text messaging and calls home.
Its possible to get much cheaper calls and receive for free by switching Sim card. To use another network's Sim in your mobile you'll need to make sure your iPhone is unlocked. Once unlocked, to switch Sim just take out the existing card and put the new one in; yet this does mean people will need to call you on a different number.
Which type of Sim to buy. There are two main options...
Buy a local Sim card (the cheaper route)
This is a specific Sim card for the country you are going to. Generally it works out cheaper to do this, however if you travel regularly to different countries, it means picking one up for each journey and giving out a new number each time.
Get an international roaming Sim card.
Here you use a special multi-country Sim card. While not quite as cheap as a local card, you only need to buy it once, and keep the same number wherever you are.
