4G is the name given to the fourth generation of mobile networks, just as the previous generation is called 3G. It allows network providers such as O2, and Vodafone to provide better network services, for instance support for video calls, wireless voice telephony, mobile TV and high-speed web browsing. 4G is around five times faster than existing 3G services. Theoretically it can provide download speeds of up to 100Mbps.

4G LTE is a type of 4G technology. This stands for Long Term Evolution. 4G LTE aims to offer users even faster, more reliable mobile broadband internet for devices like smartphones, tablets and laptops.

Micro and Nano SIMs are smaller versions of the regular SIM cards. The micro-SIM is a smaller type of SIM that was first used in the iPhone 4 and the Nano SIM is around 40% smaller. Most smartphones will use either of these instead of the traditional SIM.

If you have recently purchased a phone which requires a Micro or Nano SIM a SIM card cutter can be used which cuts the regular SIM to the size required. A SIM adapter can also be used if you need to put a smaller SIM into a phone which requires a larger SIM.

VOIP is an acronym for Voice Over Internet Protocol, or in more common terms phone service over the Internet.
If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company.

Call your current provider and ask for a PAC code.

• They must give you one (or tell you why they can't) within two working days.
• It's free once you've paid any outstanding bills and disconnection fees.
• You must get a PAC code before you disconnect your old phone. If you disconnect without getting a PAC, you won't be able to keep your old number.

• You can normally increase your tariff at any time, but lowering it will depend on when your contract started, and how long you've been on your current tariff. You may be required to pay off the remainder of your current contract (what you agreed to pay each month, multiplied by how long you have left on it), before you can begin a new one.
• If you change your tariff it will take effect from the date your monthly allowance is allocated.
