Alternative methods of extraction SIM-cards (if there is no paper clip)

Is the paper clip lost and the tray needs to be opened urgently? Here are 3 proven methods that will work in most cases:

Method 1. Office paper clip

Untighten the regular paperclip so that you get a straight metal bar length of 3-4 cm. Insert it in the groove and press. The main thing is that the diameter of the paperclip does not exceed 0.8 mm, otherwise it will not enter the hole.

Method 2. Needle from syringe

A medical needle (such as an insulin syringe) is perfect — it's strong and has the right diameter. Remove the cap, insert the needle into the groove and press. Be careful — after removing the tray, remove the needle to a safe place.

Method 3: Headphones with metal plugs

If you have a 3.5mm headphone (like the Xiaomi Piston), you can gently insert the plug into the groove and press it, and the downside is that you're at high risk of damaging the headphone jack, so only use it as a last resort.

❌ What can't be done:

• Use a knife or scissors (you can hurt or scratch the body).
• Puncturing the groove with a pin (it will break and get stuck inside).
• Heat the body with an open fire (for example, a lighter).
