Some combined factors such as coverage, location, network traffic and the type of data being transmitted have an impact on the speed.
Try the following tricks:
- Turn your phone off and back on again
- Remove your SIM card from your phone and insert again
- Insert the SIM card into a difference device
- Move outdoors or near a window if you are indoors or in a basement
If you've run out of data, then that’s the culprit! When you’ve run out of data, your speeds are managed. To get back to 4G+ speeds, just purchase a Boost/an Add-on, turn on/off airplane mode and you'll be back up to high speeds!
