4. If you are using a China Unicom or China Telecom SIM card in the secondary card slot
(upper card slot, nano-SIM card), you will only be able to access the Internet using a much
slower 2G GPRS or EDGE network.
10.25 Why can't I access LTE services when using an LTE
phone?
1. You must use an LTE-enabled SIM card in order to access LTE services. Contact your
carrier to order a replacement SIM card.
2. If you can only access LTE in some locations, then LTE services are not yet available in all
areas. China is still in the process of expanding 4G network coverage. In many regions there
may be no 4G network available or the 4G signal strength may be very weak, therefore it is
normal not to be able to access 4G networks.
Check your settings: Go to Settings > More > Mobile Networks > Preferred network type.
If WCDMA/GSM auto is selected, switch to LTE/WCDMA/GSM auto.
3. If you have already activated 4G services, check that your phone supports the 4G frequency
used by your carrier.

1. When the Wi-Fi network is available, use the Wi-Fi network.
2. Turn off your data service when you don't need to go on the Internet.
3. When you surf the Internet, set your phone to block images on web pages.
4. On the browser screen, open the option menu, and touch No images/Off. Wait until the
icon is changed to No images/On.
5. If not needed, turn off background data synchronization.
Open the notification panel and touch .
6. Close networked applications not in use.
Open the list of recently used applications. Flick left or right across an application or
touch to close it, or touch to close all applications simultaneously.
10.27 Why can't I connect my phone to an OTG cable?
1. When you connect an OTG cable to your phone, the phone functions as a card reader.
Check whether your phone supports a microSD card and the USB drive function. If not,
use another phone.
2. Check whether the microSD card was inserted into the phone correctly.
3. If a microSD card has already been inserted, check whether USB drive mode is activated
on the connected phone.
4. When an OTG cable is used to connect your phone to a USB storage device, the phone
provides power to the device. Certain USB storage devices that have a high power rating
such as portable hard drives or phones may not function properly.
