P8 Smartphone FAQs
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 a non-standard SIM card be inserted into the
card tray?
Your phone's SIM card thickness is designed based on the industry standards. Non-standard
cards can't be inserted into the card tray because they may damage the card tray. You are
suggested to use a standard SIM card. Do not use card tray adapters.

Check whether your phone model and the SIM card type are compatible and whether the
settings of the primary and secondary cards are correct.
Restart your phone after you insert the SIM card.
If the phone still fails to detect the SIM card, back up the data and restore the factory
settings. Then, insert the SIM card and check whether the phone can detect it.
Check whether the SIM card can be identified by another phone and whether the phone
can detect another SIM card.
Check whether the SIM card is standard (standard SIM cards are strongly recommended).
If not, back up the contacts in the SIM card and replace it with a standard SIM card at the
customer counter. Your phone may not detect a cut SIM card or a nano-SIM card
equipped with a card holder. These cards may damage the card tray.
If the problem persists, the card tray may be damaged or other problems exist. You are
suggested to make a detection on your phone at the maintenance center.
