10.20 Does my phone support SIM card hot swapping?
No.
10.21 Why can't I delete the data usage record for the
current date?
You can't delete the data usage record from the running notifications. You can delete the data
usage record in Phone Manager in the following path:
Phone Manager > Usage > Data plan settings > Display traffic information in
notifications
10.22 Why is my daily data usage refreshed to my monthly
data limit every day after my data usage exceeds the
monthly limit?
Your phone only displays your data plan usage status. After you have used up all the data
volume covered in your data plan, the daily data usage will be refreshed to your monthly data
plan limit.
10.23 Why can't I register on a 4G network at the end of
the month in some regions?
When you have used up your data allowance for a particular month, your carrier may disable
4G services for your SIM card, meaning that you will not be able to register on a 4G network.
Check with your carrier to see if you have used up your data allowance. If so, disable 4G on
your phone until the beginning of the next month to prevent signal interference.
10.24 Why is the mobile data connection still very slow
after switching to an LTE phone?
1. Not all regions are covered by an LTE network, therefore your phone may not be connected
to an LTE network. Check whether '4G' is displayed in the signal bar. If not, there is no 4G
coverage.
2. You may be in an area with a poor signal. Not all areas have a reliable mobile data network
(especially 3G), which may slow down your data connection. If you are using a China
Telecom SIM card, the default access point is set to CTWAP (a WAP network). You are
recommended to switch the access point to CTNET for a faster Internet connection. To change
the access point, go to Settings > Mobile Networks > Access Point Names.
3. The speed of the server may be slow.
