Network Coverage Type | Average Download Speed* | Average Upload Speed* | ![]() |
| 3G broadband (HSDPA) | 500 kbps – 1500 kbps | Up to 384 kbps |
| GPRS | 20 kbps – 40 kbps | 10 kbps – 15 kbps |

Yes, both uploads and downloads are deducted from your credit.
return to topPoor signal strength is the most common reason for the internet slowing down.
Physical obstructions, such as being indoors, underground, behind buildings or behind other land masses, can reduce your level of signal strength.
If you’re having problems with signal strength you can try moving to a different location such as outdoors, closer to a window, or to higher elevation. If you’re using a USB modem try using a USB extension cable and place the modem near a window or at higher elevation.
