DIALING GUIDE

Step-by-Step: Call the UK from Greece

Follow these steps to correctly dial any UK landline or mobile number from Greece. The format is the same whether you're calling from a Greek landline, mobile, or using Sayfone in your browser.

1
Dial Greece's exit code: 00
From any Greek phone (landline or mobile), start by dialing 00 to access the international network. On a mobile phone, you can also press and hold the 0 key to produce the + symbol, which works the same way.
```
00 ...
```
2
Dial the UK country code: 44
Immediately after the exit code, dial 44 — the international country code assigned to the United Kingdom. This routes your call to the UK telephone network.
```
00 44 ...
```
3
Drop the leading 0 and dial the UK number
UK numbers start with a 0 when dialed domestically (e.g., 020 for London, 07 for mobiles). When calling internationally, remove that leading 0. So 020 7946 0958 becomes 20 7946 0958, and 07700 900123 becomes 7700 900123.
```
00 44 20 7946 0958 (London landline) or 00 44 7700 900123 (UK mobile)
```
Press call or use Sayfone
Hit the call button on your device. Alternatively, open Sayfone in your browser, enter the UK number, and call at just $0.08/min with no app to install — ideal if you're on a Greek Wi-Fi network or want to avoid roaming charges.

IMPORTANT RULES

Dialing Rules for Calling the UK from Greece

Keep these rules in mind to avoid common mistakes and ensure your calls connect on the first try.

Always drop the leading 0

UK numbers begin with 0 for domestic dialing (e.g., 020, 0161, 07). When dialing from Greece, always remove this 0 after entering +44. Dialing +44 020 will not connect.

UK numbers vary in length

UK phone numbers (after the country code) are typically 10 digits for landlines and 10 digits for mobiles. London uses a 2-digit area code (20) with 8-digit subscriber numbers; other cities use 3–5 digit area codes with correspondingly shorter subscriber numbers.

Greece uses exit code 00

When calling from a Greek landline, you must dial 00 before the country code 44. On mobile phones, you can use the + symbol instead, which automatically substitutes for 00.

UK freephone numbers may not work internationally

Numbers beginning with 0800 or 0808 are UK freephone numbers and typically cannot be reached from outside the UK. Similarly, service numbers starting with 084, 087, or 09 may not connect when dialed internationally.

Mobile numbers start with 7 internationally

UK mobile numbers begin with 07 domestically. Internationally, after +44, they start with 7. The full international format is +44 7XXX XXXXXX (11 digits total including country code).

TROUBLESHOOTING

Common Issues When Calling the UK from Greece

If your call isn't connecting, check these common problems before trying again.

Call not connecting at all

Double-check you dialed 00 (or +) before 44. Verify you dropped the leading 0 from the UK number. For example, 020 7946 0958 should be dialed as 00 44 20 7946 0958.

Getting a 'number not recognised' message

UK numbers vary in length depending on the area code. London numbers are 020 + 8 digits; other cities may be 01xxx + 5 or 6 digits. Make sure you have the complete number including the area code.

Cannot reach a UK freephone number

UK 0800 and 0808 numbers generally do not accept international calls. Ask the recipient for an alternative geographic or mobile number you can reach from Greece.

High charges on your Greek mobile bill

International calls from Greek mobile carriers can be expensive. Use Sayfone via your browser over Wi-Fi to call the UK at $0.08/min — no SIM swap or app install needed.

Poor call quality or dropping calls

If calling over a cellular network, try moving to a location with a stronger signal. For browser-based calling with Sayfone, ensure a stable Wi-Fi connection with at least 1 Mbps upload speed.
