To check your voicemail from your wireless phone while roaming; dial 1+671+488-0000. If asked for your Voicemail password, enter your four digit password. Roaming rates charges apply.
To check your voicemail from a landline, dial 1+671+488-0000 and then follow the voice prompts, and input the ten digit number. I.e. 671- then the seven digit MPULSE number, and then press star * then dial the ten digit MPULSE number.

What is the cost for roaming service?

What is a GSM world phone?

GSM world phones are devices that operate on international frequencies. These can include "tri-band" phones/devices (which operate on three of the four GSM frequencies) and "quad-band" phones/devices (which operate on all four of the GSM frequencies). GSM networks in North and South America operate at frequencies of 850 or 1900 MHz, while most networks in other countries operate at frequencies of 900 or 1800 MHz GTA also offers phones that operate on 3G technology at 2100 MHz to roam in Japan and South Korea. GTA recommends quad band and 3G phones/devices for most international travelers. Since these wireless devices operate on all of the international GSM frequencies, you ensure the broadest international coverage available.

What steps should I take if my Roaming services are not working?

If you are having difficulty using Voice or data services while roaming, try these troubleshooting steps:
- Power cycle your wireless phone by turning it off and then turning it back on.
- Try manual scanning using the Network settings on your wireless phone. Select a network other than the one on which you are currently registered. If you are still encountering problems please contact our 24hr Customer Service Support at (671) 644-4482.

When using my iPhone, BlackBerry or other Smartphone, do I still have unlimited data usage when I travel outside of Guam?

You will be charged for data usage if you choose to use data on your wireless phone while roaming. For pricing, please contact our 24hr Customer Support Center at (671) 644-4482.

How do I minimize my data charges when I use my iPhone while roaming?

The iPhone has many robust applications, so it's natural for users to transfer more data on their iPhone than they would using other handsets or PDA devices. GTA offers the following tips to keep your bill predictable:
- Know the roaming rates in the country that you are roaming in.
- Use your device responsibly
- Use of data applications and browsing will increase data usage. These applications can use data without user intervention so we recommend that you minimize your usage of data applications while roaming.
- Utilize Wi-Fi networks.
- Turn Data Roaming “ON” or “OFF” when needed. SETTINGS > GENERAL > NETWORK > Data Roaming > OFF/ON.
