Helpful Tips About GSM
Roaming Your GSM phone assumes the characteristics of the wireless network in each country you visit. So if you are traveling in Italy, your phone will work like a local Italian wireless device.
Upon arrival, you should learn how to make local calls in the country visited.
While roaming outside the U.S., be sure to make all international calls using the international format (+, country code, number). For example, to place an international call back to the United States, dial +1, then the area code and number (the U.S. country code is "1"). In most GSM
devices, holding down the 0 key will cause the + sign to appear.
The 911 emergency number is unique to the U.S. In many European countries, the emergency number for police, fire, or ambulance is 112. Outside Europe, emergency numbers will vary by country.
When you are abroad and turn on your wireless phone, it will automatically search for a wireless network. Registration usually occurs within 30-40 seconds. When the name or network number of the local operator is displayed, your phone should be ready to use.
After your device registers abroad, customers with a data-centric device but without an international plan/package, may receive a free SMS
message from AT&T advising the applicable data rate and where to go/call for more information (rates are sent to California consumers without an international plan/package, regardless of device type). Before traveling abroad, review our discount packages for calling, messaging or using data abroad.
Like any other appliance, you will need a universal phone charger and plug adapters for the countries you are visiting.
In some countries, using a wireless phone while driving is prohibited. Contact the local tourist information office for regulations that may apply.
If you have problems or questions while roaming outside the U.S., contact AT&T by calling +1-916-843-4685 (a free call from your wireless phone).
