GTT Guyana

The GTT Guyana sim features unlimited free incoming calls and unlimited free incoming text messages while you are in Guyana. We also have a sim option including data service for iPhone, iPad, smartphones and tablets. The apn for data is gtt.
The sim card will roam worldwide, so you can insert the sim card into your unlocked GSM phone at home prior to travel for testing. Insert sim and turn your phone on. Call your GTT Guyana number from a land line to make sure it rings. GTT Guyana uses the 850Mhz/1900Mhz GSM band so make sure you have a quad band GSM phone ready for your trip.

How it works:

You can place your order here at mrsimcard.

We will process and ship the order. During processing we will send an email asking for your arrival date. Once you respond, we will schedule the activation of your sim 1 to 2 days before arrival.

You can test the sim prior to travel to ensure compatibility with your phone. You will arrive, insert the sim, power cycle the device and configure data per the instructions sent to you. Configuration changes by sim and destination. You can even add money to your line before and during travel. While in country you can visit a GTT store or authorized retailer to recharge locally. Its Easy Cheesy!

Your Phone Number

GTT Guyana Sim - Phone

Your phone number is written on the SIM. It’s the number beginning 592:
(592) is the country code, the other SEVEN digits are the number XXX-XXXX
To call the number above from the USA or Canada, I would dial 011-5926150XXX or from Europe - 005926150XXX.

How to Dial Internationally

To place a call outside of the Guyana to the USA or Canada you must dial +1 or 001 followed by the 10 digit number.
To call the rest of the world - the format is: 00 + COUNTRY CODE + AREA CODE + NUMBER
