When you dial a phone number that starts with “002,” you are attempting to make an international call from within the United Kingdom. The correct prefix for international calls from the UK is actually “00,” so if you accidentally dial “002,” your call may not be successful. However, if you do manage to successfully dial the number, there are a few things that could happen depending on a few factors.

Location of the Number
The first thing to consider when dialing an international number is the location of the number. Different countries have different dialing codes and phone number formats, so it’s important to know the correct code and format for the country you are trying to call.
For example, if you are trying to call a number in the United States, you would need to dial “001” before the phone number. If you are trying to call a number in France, you would need to dial “0033” before the phone number.
If you dial “002” instead of the correct prefix, you may not be able to connect to the phone number you are trying to call. In some cases, you may hear a recording stating that the call cannot be completed as dialed.
Carrier Network
Another factor that could impact what happens when you dial a number starting with “002” is the carrier network you are using. Different mobile network operators and landline providers may have different policies and restrictions when it comes to making international calls.
For example, some carriers may block international calls altogether or may charge additional fees for international calling. In some cases, you may need to contact your carrier or provider to enable international calling on your account before you can make an international call.
International Call Rates
The cost of making an international call can vary depending on a number of factors, including the location you are calling, the length of the call, and the carrier network you are using. Some carriers may charge a per-minute rate for international calls, while others may charge a flat fee.
If you are dialing a number starting with “002” in an attempt to make an international call, it’s important to be aware of the potential costs involved. Some carriers may charge significantly higher rates for international calls, and you could end up with a hefty bill if you are not careful.
Alternative Methods for Making International Calls
If you are having trouble making an international call by dialing a number starting with “002,” there are a few alternative methods you can try. One option is to use a calling card, which allows you to make international calls using a prepaid account.
Another option is to use a VoIP (Voice over Internet Protocol) service, such as Skype or WhatsApp. These services allow you to make voice and video calls over the internet, often for free or at a much lower cost than traditional phone calls.
Conclusion
In conclusion, dialing a number starting with “002” is not the correct prefix for making international calls from the United Kingdom. If you do attempt to dial a number starting with “002,” your call may not be successful or may be subject to additional fees or charges.
If you need to make an international call from the UK, it’s important to know the correct dialing code and phone number format for the country you are trying to call. You should also be aware of the potential costs involved and consider alternative methods for making international calls, such as using a calling card or a VoIP service.
