How to Dial an International Number with an Android Phone
To make an international call with your Android phone, you merely need to know the foreign phone number. The number includes the international country-code prefix, followed by the number.
Before dialing the international country-code prefix, you must first dial a plus sign (+) when using the Phone app. The + symbol is the country exit code, which must be dialed to flee the national phone system and access the international phone system.
For example, to dial Finland on your phone, you dial +358 and then the number in Finland. The +358 is the exit code (+) plus the international code for Finland (358).
To produce the + code in an international phone number, press and hold down the 0 key on the Phone app’s dialpad. Then type the country prefix and the phone number. Touch the Dial Phone icon to complete the call.
Most cellular providers surcharge when sending a text message abroad. Contact your cellular provider to confirm the text message rates. Generally, you’ll find two rates, one for sending and another for receiving text messages.
If texting charges vex you, remember that e-mail has no associated per-message charge. You also have alternative ways to chat, such as Google Hangouts and Skype.
In most cases, dialing an international number involves a time zone difference. Before you dial, be aware of what time it is in the country or location you’re calling. The Clock app can handle that job for you: Summon a clock for the location your calling and place it on the Clock app’s screen.
Dialing internationally also involves surcharges, unless your cell phone plan provides for international dialing.
The + character isn’t a number separator. When you see an international number listed as 011+20+xxxxxxx, do not insert the + character in the number. Instead, dial +20 and then the rest of the international phone number.
International calls fail for a number of reasons. One of the most common is that the recipient’s phone company or service blocks incoming international calls.
Another reason that international calls fail is the zero reason: Oftentimes, you must leave out any zero in the phone number that follows the country code. So, if the country code is 254 for Kenya and the phone number starts with 012, you dial +254 for Kenya and then 12 and the rest of the number. Omit the leading zero.
Know which type of phone you’re calling internationally — cell phone or landline. The reason is that an international call to a cell phone might involve a surcharge that doesn’t apply to a landline.
