How to Call Internationally

If you are searching for how to call internationally, this guide explains everything in a simple way. You will learn the correct international calling format, common mistakes to avoid, and how Slick helps you make affordable international calls with ease.
Slick offers international calling services designed for people who want a simpler and more cost-effective way to stay connected with family, friends, and business contacts around the world.
What Is an International Call?
An international call is a phone call made from one country to another. Unlike local calls, international calls require a special dialing format so the network knows exactly where to connect your call.
A typical international number includes:
- A plus sign (+) or exit code
- A country code
- An area code if needed
- The local phone number
Using the correct format is important because even one wrong digit can stop the call from connecting.
How to Call Internationally Step by Step
If you want to know how to make an international call, follow these simple steps.
1. Start With the Plus Sign (+)
The easiest way to dial an international number is to start with the plus sign (+). On most smartphones, you can add it by pressing and holding the 0 key.
Example format:
+ [Country Code] [Area Code] [Phone Number]
This is the most common and easiest international dialing format.
2. Enter the Country Code
Every country has its own calling code. This tells your network which country you want to call.
Some common country codes include:
- United States/Canada: +1
- United Kingdom: +44
- Pakistan: +92
- India: +91
- Saudi Arabia: +966
Entering the correct code is essential for the call to go through.
3. Add the Area Code
Some countries require an area or city code before the local phone number. In many cases, the first zero used in local dialing is removed when dialing internationally.
That is why it is always best to check the correct international number format before calling.
4. Dial the Local Phone Number
After entering the country code and area code, add the rest of the local phone number. Double-check the full number before placing the call.
International Calling Example
Here is a simple example.
If a UK number is written locally as:
020 1234 5678
You would dial it internationally as:
+44 20 1234 5678
Notice that the starting zero is removed and replaced with the UK country code. This rule applies to many countries, although formats can vary.
Common Problems When Calling Internationally
Many people face the same issues when making international calls.
Wrong Number Format
A very common mistake is entering the local number exactly as it appears without changing it to international format. Missing the country code or adding an extra zero can cause the call to fail.
High International Calling Rates
Traditional mobile carriers often charge expensive rates for international calls. These costs can become very high if you call abroad regularly.
Hidden Charges
Some providers advertise cheap calls rates but later add extra fees. This makes international calling more expensive than expected.
Poor Call Quality
Weak connectivity or poor routing can lead to dropped calls, bad voice quality, or delays during the conversation.
How to Make International Calling Easier and Cheaper
The easiest way to make international calls is to use a service built specifically for international communication instead of depending only on traditional mobile networks.
A good international calling service should offer:
- Affordable calling rates
- Clear and transparent pricing
- Easy dialing and country code support
- Reliable call quality
- Flexible top-up options
- Access from anywhere with internet
This is where Slick can help.
