World Of Mobile & Telecommunication.

Along with the obvious convenience and quick access to help in emergencies big and small, mobile phones can be both economical and essential for travelers trying to stay connected. An example: it's not uncommon for mobile calls to be cheaper than local calls made from some hotel rooms. European hotels in particular are known for excessive phone tariffs -- three days of connecting locally at a five-star hotel in Amsterdam once cost me more than $100! However, Europeans have no lock on this practice -- at a hotel in Quito, Ecuador local calls cost USD$.50 a minute! In contrast, many mobile providers offer exceptional plans that include generous amounts of air time, no long distance charges, and in some cases very reasonable international roaming rates.
In other situations, a mobile phone may simply be the only way to get online. This was the case when I stayed at a lovely historic hotel in Krakow's old town -- unfortunately, the ancient phone lines were too noisy to allow a modem connection at any speed. However, thanks to a GSM phone and modem, I could connect with ease.
