Do Foreign Cell Phones Work in India?

Your phone may not work in India with any of the local SIM cards unless it is unlocked. In most parts of the world, mobile phones are locked to their telecom carriers and only they can unlock the phones for you.

If you have an unlocked GSM phone that will accept the SIM cards of other carriers and that runs on the same GSM frequencies India uses, you won't have to worry about your phone not working India.

A quad-band unlocked GSM phone will be compatible with most GSM networks worldwide, including India. However, US cell phone carriers usually lock GSM phones to prevent customers from using other companies' SIM cards. In order for the phone to be unlocked, certain conditions must be met.

Indian SIM Cards

There are two types of SIM cards in India, to help you narrow down your choices. You can buy a prepaid SIM card in India, which is where you pay beforehand to use services like calling, data, and texting. However, there is a downside of getting a prepaid SIM card such as needing a constant top-up.

The other is a postpaid SIM card, where you are billed after having used the services like calling, data, and texting. However, they cost more than the prepaid plans.

The most commonly used service providers in India are Airtel, Vodafone, Reliance, Idea, Jio and BSNL which is the only government-run telecom service. Out of these, Airtel, Vodafone, Jio, and BSNL work well in most cities. Jio, Airtel and Vodafone offer the best coverage across the country.

How to Get a SIM Card in India

Prepaid SIM cards, with a maximum three months validity, can be purchased inexpensively in India.

The easiest way is to get them at the airport. Most international airports have counters that sell them. When you land in in India at one of the international airports, head to the provider of Airtel or Vodafone in the arrival section and ask for a Prepaid SIM card. You will need your passport, Indian visa, and a photograph.

For Airtel, the SIM card price is 400 rupees for foreigners, and it includes talk-time, daily internet, and SMS for a month. The SIM is activated within 2 to 3 hours. The only downside of this method getting it at the airport is that it is costlier than what you can get in the city.

Alternatively, you can buy them at cell phone stores or retail outlets of phone companies.

Making International and Local Phone Calls in India

To make calls within the same city in India you only need to dial the respective phone number. If you want to make calls to different regions in India you need to dial a special prefix, the so-called Subscriber Trunk Dialing or STD, and then the number itself. STD's can be found at

If you want to make international calls from India, first you need to dial 00 which is the international access code for India, followed by the country code, the area code, followed by the local number.

Internet cafes are another option. They are a great way of staying in contact with your family and friends. Internet cafes in India charge between 10 to 30 rupees per hour. They usually have broadband connections.

However, the Wi-Fi connection in Internet cafes might not always be a strong one as many people use it at the same time. You may only be able to check your email.

To ensure that you are connected to the Internet wherever you go in India, you can opt to buy a pocket Wi-Fi device. This is perfect if you are travelling with families or groups.
