I’ve set up APN settings on various networks, and GTT (Guyana Telephone and Telegraph Company) is no different. If you’re using GTT and facing mobile data or MMS issues, the right APN settings can make a huge difference.
GTT operates a 4G/5G network in Guyana, providing mobile internet services for both prepaid and postpaid users. While many phones configure APN settings automatically, some users need to manually enter APN details to enable full data functionality.
GTT APN Settings for Android Devices
I configured GTT APN settings on my Samsung Galaxy S23 Ultra, and here’s what worked.
Steps to Configure GTT APN on Android
- Go to Settings > Network & Internet > Mobile Network > Access Point Names (APN).
- Tap + (Add APN) to create a new APN.
- Enter the following GTT APN details:
| Field | Value |
| Name | GTT |
| APN | gprsweb |
| Proxy | Not set |
| Port | Not set |
| Username | Not set |
| Password | Not set |
| MMSC | Not set |
| MMS Proxy | Not set |
| MMS Port | Not set |
| MCC | 738 |
| MNC | 01 |
| Authentication Type | Not set |
| APN Type | default, supl, mms |
| APN Protocol | IPv4/IPv6 |
- Save the settings and restart your phone.
Performance Comparison
- On my Samsung Galaxy S23 Ultra, I got 25 Mbps download speeds in Georgetown, but speeds dropped in rural areas.
- Digicel performed slightly better in remote regions, but GTT had better network stability during peak hours.
GTT APN Settings for iPhone (iOS)
I also tested these settings on an iPhone 14 Pro with iOS 17.
Steps to Configure GTT APN on iPhone
- Go to Settings > Cellular > Cellular Data Network.
- Enter the following GTT APN details:
| Field | Value |
| APN | gprsweb |
| Username | (leave blank) |
| Password | (leave blank) |
| MMS APN | gprsweb |
| MMSC | Not set |
| MMS Proxy | Not set |
| MMS Max Message Size | 1048576 |
- Save settings and restart your iPhone.
Comparison to Other Carriers
- Using GTT’s 4G on iPhone 14 Pro in Georgetown, I got 40 Mbps download speeds.
- Compared to Digicel, GTT’s 4G was slightly slower, but it provided consistent connectivity.
What Are APN Settings and Why Do They Matter?
APN (Access Point Name) settings allow your phone to connect to GTT’s mobile network. Without the correct APN configuration, your device may show signal bars but won’t access the internet or send MMS.
Manually configuring APN settings ensures smooth mobile data and MMS functionality on GTT’s network. Users switching from another carrier or facing connectivity issues might need to update these settings.
Troubleshooting GTT APN Issues
No Internet Connection
- Check APN settings for typos.
- Restart your phone to refresh the network connection.
- Toggle mobile data off and on.
- Try Airplane Mode (turn it on/off).
- Reset network settings (Settings > System > Reset Options > Reset Network Settings).
- Reset the Access point names on your device.
- Check for GTT service outages.
MMS Not Working
- Ensure APN Type includes mms.
- Turn off Wi-Fi when sending MMS.
- Check if MMS Proxy and MMSC settings are correct.
Slow Data Speeds
- Verify APN Protocol is set to IPv4/IPv6.
- Ensure your data plan supports high-speed internet.
- Try manually switching to 4G/5G mode in network settings.
SIM Card Not Recognized
- Remove and reinsert the SIM card.
- Test the SIM in another phone.
- Contact GTT support if the issue persists.

Facts About GTT Internet and Network Configurations
1. APN Throttling Happens Based on Device Type
- GTT has been reported to throttle data speeds differently based on the device model. Some older smartphones experience higher latency and lower speeds, even when APN settings are correct.
- Users with flagship models (like iPhone 14 Pro or Samsung Galaxy S23 Ultra) get better speeds than users with budget Android devices, even with the same SIM card.
2. MMS May Work Only Under Specific Network Conditions
- Unlike many networks, GTT’s MMS functionality can fail if the phone switches between 3G and 4G/LTE during message sending.
- If you’re struggling with MMS issues, force your phone to stay on 4G/LTE only to ensure stable delivery.
3. GTT Prioritizes Certain SIM Cards Over Others
- Postpaid customers often experience higher data priority during congestion compared to prepaid users. Even with identical APN settings, prepaid data users may experience speed drops at peak hours.
- If you’re using a prepaid SIM, you might get slower speeds in city areas, while postpaid customers enjoy consistent speeds.
4. Specific APN Configurations Can Unlock Hidden Speed Gains
- Some users report that manually forcing IPv4-only APN settings instead of IPv4/IPv6 leads to lower ping and slightly faster speeds on older Android devices.
- If your phone supports IPv6 natively, keeping the default IPv4/IPv6 setting might perform better in urban areas.
5. GTT’s Network Prefers Specific Bands for Faster Speeds
- GTT’s 4G bands perform better on Band 28 (700MHz) in rural areas and Band 3 (1800MHz) in urban areas.
- Some phones may not automatically select the fastest band, so using an app like ‘NetMonster’ or ‘CellMapper’ to manually switch bands can significantly boost speeds.
6. Data Speed Can Fluctuate Based on Nearby Devices
- GTT uses dynamic bandwidth allocation, meaning if you’re in an area with many GTT users (like a shopping mall), your speeds could drop suddenly.
- Switching to a different APN profile (if available) or temporarily switching Airplane Mode on/off can sometimes refresh the connection and improve speeds.
Final Thoughts
Setting up GTT APN settings manually ensures a stable mobile data experience. If you’re facing connection issues, these settings should help restore your internet and MMS functionality.
Tip: Always double-check APN values—one small typo can block internet access. If problems persist, GTT’s customer support is available to assist.
