DIALING GUIDE
Follow these steps to place a call to any Indian mobile or landline number from a UK phone or browser-based calling service.
From a UK landline, dial 00. From a UK mobile phone, you can press and hold 0 to get the + symbol, or simply type +.
00 or +
Enter 91 immediately after the exit code. This routes your call to India's telephone network.
00 91 or +91
For an Indian mobile number, dial the full 10-digit number (starting with 6, 7, 8, or 9). For a landline, dial the area code without the leading 0, followed by the subscriber number. The area code plus subscriber number also totals 10 digits.

IMPORTANT RULES
Keep these rules in mind to make sure your call connects successfully.
Indian domestic numbers use a trunk prefix of 0 (e.g. 011 for Delhi, 022 for Mumbai). When dialing from the UK internationally, drop this leading 0. Dial 11 for Delhi, 22 for Mumbai, and so on. Mobile numbers dialled internationally do not include a leading 0.
Indian mobile numbers are exactly 10 digits long and start with 6, 7, 8, or 9. They do not use an area code. Dial the full 10-digit number after +91.
Indian landline area codes range from 2 to 4 digits. Major metros use 2-digit codes (Delhi: 11, Mumbai: 22). The area code plus subscriber number always totals 10 digits.
The UK international exit code is 00. On a mobile phone, you can use the + symbol instead, which works universally. Both methods route your call internationally.
Toll-free numbers (e.g. 1800 numbers) and some premium or short-code numbers within India may not be reachable from outside the country. Stick to standard 10-digit mobile or landline numbers for international calls.
TIMING TIPS
India Standard Time (IST) is UTC+5:30 year-round. The UK shifts between GMT (UTC+0) in winter and BST (UTC+1) in summer, so the gap changes seasonally.
During UK winter (GMT), India is 5 hours 30 minutes ahead. During UK summer (BST, late March to late October), India is 4 hours 30 minutes ahead. India does not observe daylight saving time.
UK Morning → India Afternoon

TROUBLESHOOTING
If your call to India isn't connecting, check these common problems.
If you included the domestic trunk prefix 0 before the area code (e.g. dialling +91 011 instead of +91 11), the call will fail. Always drop the leading 0 when dialling India from abroad.
Indian phone numbers (area code + subscriber number for landlines, or the full mobile number) should total exactly 10 digits after the country code. If you have fewer or more, double-check the number.
Some UK mobile plans or landline providers require international calling to be activated before you can dial overseas. Contact your UK provider if calls are being blocked.
Some special numbers within India — such as toll-free (1800) or short codes — may not be reachable from outside the country. Use a standard mobile or landline number instead.
