How do you dial Thailand from Iraq?

India uses telephone country code +91, and you must also drop the trunk prefix 0 from the beginning of the Indian telephone number. For example, Mumbai's area code 022 becomes +91 22 in international format.

The access prefix for international calls from Thailand is 00.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
