8.4 Why can't I insert the SIM card into my phone
smoothly?
1. Make sure you use a standard nano-SIM card. Do not 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 card at the customer counter.
2. If the card tray is inserted into the phone tightly 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 feel the plugging conditions.
8.5 Why are the outer surfaces of the SIM and microSD
card trays and the surfaces of the aluminum decorations
uneven?
The phone surface evenness at delivery is compliant with the quality control standards of the
industry. If the unevenness is obvious, take your phone to an authorized Huawei service
center and check whether there is a quality issue.
8.6 Why doesn't the SIM card slot have a spring?
The structure of the SIM card tray adopts the ultra-thin design, and the card holder is in a
leverage structure. You can use the delivery-attached eject tool in the gift box to take out the
card tray.
8.7 Why are the two gaps on the two sides of the SIM card
tray harsh?
Check whether the card tray is convex or concave. According to the design, to ensure that the
convex part is not harsh, there should be a 0.1 mm concave manufacturing tolerance. If the
problem is serious, take your phone to an authorized Huawei service center and check
whether there is a quality issue.
8.8 How can I identify the SIM or microSD card insertion
direction?
The internal of the card tray indicates SIM card 1 and SIM card 2 positions. You can also refer
to the protective film instructions on the rear surface of the phone.
