Frequently Asked Questions
GSM Inbound Roaming

GSM Outbound Roaming out

What is GSM Roaming Service?
GSM roaming is the ability to use your cellular phone (and number) while traveling away from your home network. This service allows you to connect to the GSM network of the location you are visiting without buying another SIM card.

For example, IT&E GSM customers from Guam can come to Palau and make both local and international calls with their GSM phones as soon as they step off the plane, without having to purchase a PNCC SIM card. They will be billed by IT&E for all calls made while roaming in Palau on their regular monthly bill, not by PNCC.

Roaming between G Top SM networks offers the convenience of a single number, a single bill and a single phone with worldwide access.
How does GSM Roaming work?
Mobile network operators must establish Roaming Agreements to govern the exchange of customer billing data for their customers who “roam” on the visited network.

For example, when IT&E customers visit Palau and make calls with their cell phones, PNCC’s network collects the call detail records and sends them to IT&E (who then bills them for roaming in Palau).

If the visited network is in the same country as the home network, this is known as National Roaming. If the visited network is outside the home country, this is known as International Roaming (the term Global Roaming has also been used).

Roaming service is a convenient, premium service that is mostly used by customers with postpaid accounts (prepaid roaming is not very common).
How can visitors to Palau roam on the PNCC Wireless network?
Visitors to Palau who want to roam on the PNCC Wireless network must have a GSM phone that can operate on the GSM-900 band. Most modern phones are multi-band (e.g. 850, 900, 1800 and 1900 MHz).

Their home operator must also have a roaming agreement with PNCC so they can be billed for the services when they return home.

Upon arrival in Palau, visitors (called “inbound roamers”) only have to switch on their phone. Their mobile phone picks up the radio signals from PNCC’s GSM network.

PNCC then 'authenticates' the visitor’s mobile phone with their home operator (to check if they are a valid customer, whether they are allowed to roam, etc.). If their home operator responds with a positive authentication, the visitor’s mobile phone is ready for use.

This process is completely automatic and it typically takes only a few minutes to log on to the local network. Top
Which overseas mobile operators have roaming agreements with PNCC?
As of May 2009, PNCC has a roaming agreement with IT&E (formerly PTI) that enables their Guam and CNMI customers with postpaid subscriptions to roam in Palau. PNCC is negotiating with other operators to provide ro Top aming services to their customers who visit Palau, including operators in Taiwan (CHT) and the Philippines (PLDT/Smart), with more to follow (e.g. United States operators).
How much does it cost a visitor to roam on the PNCC GSM network?
Visitors need to check with their home operator to find out what their roaming charges will be for using PNCC’s network, since PNCC does not bi Top ll the visitor directly. The visitor’s roaming rates are set by their home country operator, not PNCC, and they will be billed at home on their regular monthly bill.
When a visitor makes a call when roaming in Palau, what are the dialing instructions?
When roaming visitors call home or any other country, the dialing instructions are the same as making an international call with PNCC IDD long distance service.

Roamers have to type in the international access code (011) and the correct country code along with the country code or city code (if necessary) plus the telephone number (omitting the leading zero if any). Note: roamers may substitute a + sign for the international access code 011.

For example, to call the Guam mobile number 670 XXX XXXX when roaming in Palau, dial:
011 1 670 XXX XXXX (with no plus signs or spaces) OR +1670XXXXXXX

To dial a local number in Palau, the roamer simply dials the regular local fixed line or cellular phone number XXX-XXXX (with no access codes required).
How does a local caller in Palau dial to reach a roamer in Palau?
For a local number to call a roamer, the dialing instructions are the same as long distance dialing, because the call to a roamer originates in Palau, terminates in the roamer’s home network, and is then routed back to Palau. The usual long distance charges for calling the roamer’s home country will apply. For example, if a caller in Palau dials a roamer in Palau who is from CNMI, the charge will be 35 cents per minute plus the local Top Airtime charge (if calling from a PNCC Wireless phone).
How does a caller outside of Palau dial to reach the roamer in Palau?
When a customer is roaming in Palau, their friends and family back home can call them just as they normally wo Top uld.
What happens if the roamer receives a call?
When someone calls a roamer on their mobile phone, the call will usually be routed to the visitor’s home country and home operator (e.g. IT&E in Guam). The home operator knows where the visitor is roaming, and will then forward the call to the operator whose network you are using in the visited country (e.g. PNCC). The visited network (PNCC) will then connect the call to the roamer.

This initial routing back to the visitor’s home operator happens regardless of where the call originates, as only the ho Top me operator has the information about the visitor’s location.

Note that when roaming the visitors has to pay both for calls made and calls received; all calls received by the visitor (no matter whether they originate in Palau or overseas) are rated as long distance calls because they have to be routed through the home operator overseas.
Can visitors roaming in Palau send and receive text messages?
Yes, roamers in Palau can send and receive both local and international text messages.

Dialing instructions for roamers in Palau to send a local or international text message:

After typing in the text message just dial + country code + area code or city code (if necessary) + local number (with no spaces or plus signs). Use a + in front of the number:

Examples:
              Roamer in Palau texting to CNMI: +16702891000
              Roamer in Palau sending text to Palau: +6807759902
              Roamer in Palau texting to Taiwan: +886XXXXXXX

Dialing instructions for PNCC Wireless numbers to text a roamer in Palau:
