SIM card and appearance
9.1 Why does my phone read the contacts from the SIM
card slowly?
The reading speed of the contacts on the SIM card is affected by the SIM card performance
and the number of contacts. Generally, the reading time increases with the number of contacts.
If you are using a 4G card that supports multiple numbers for one contact, the reading speed
will be slow too.
9.2 Why can't I insert a non-standard SIM card into my
phone?
SIM cards whose thicknesses don't comply with the industrial standards can't be inserted.
Please use standard SIM cards. Don't use card adapters.
9.3 Why can't I insert the SIM card into my phone
smoothly?
1. Check that you are using the standard micro-SIM card or nano-SIM card. Don't use a
non-standard card or a manually-cut card. If you cut the card or use the card with a card
holder, the size or edges may be inappropriate, which affects the copper contacts or even
damages the card tray. Damages caused using non-standard cards are not covered by
warranty. You can replace your card with a standard one at a customer counter.
2. If the card tray can't be inserted into the phone smoothly even without the SIM card,
paint a little oil (such as cooking oil) on the card tray and wipe it clean, or use clean cloth
to clean the surface of the card tray, and then try inserting it into the phone.
3. If you are using the standard card, gently scrape the wave pattern areas on both sides of
the card tray to remove foreign matters. Then, insert an empty card tray into your phone
to check the smoothness degree.
