If you are one who does a lot of international traveling, then you will want your clients to be able to reach you from wherever you might be in the world. But what are some of the options you have when it comes to maintaining your current level of cell phone (telephone cellular) services worldwide? Do you have to buy a new plan? Do you have to pay outrageous rates? Just what is available?
When choosing an international cell phone SIM card for your GSM Cellular Phone, there are things you should consider when making a decision on which SIM card to buy. First, what is the initial calling credit (how long before you have to recharge)? Of course you should know the rate structure of both the incoming and outgoing calls. Next you should make sure that your phone and SIM card you are purchasing will be valid for the countries you intend to travel.
Because GSM utilizes the TDMA digital technology, the possibility exists to have up to three voices in one slot in contrast to the analog cell phones where only one voice had the ability to go into one slot. The GSM technology can do so because it utilizes digital compression along with its in-built encryption characteristic. Therefore, even in the event that the space used is the same, there will be more usage capacity.
