About Sim Cards

SIM cards are ID cards for your phone. They identify the number and what network it uses. SIM cards help keep your phone more secure because you can put PIN numbers on them, making it difficult for anyone else to use the phone. You can easily swap your regular card for an international SIM card when you travel. Most major mobile networks offer contract and prepaid SIM cards. eBay sellers offer many different choices, so you can easily compare your options.
