How do I insert the SIM card and memory card?

Turn off the phone, remove the back cover and battery. Insert the SIM card in the slot with the gold contacts facing down. For the microSD card, place it in the dedicated slot until it clicks. Reinsert the battery and cover.

What is the battery life and how to charge?

The 1000 mAh lithium-ion battery provides up to 6 hours of talk time and 300 hours standby. Charge using the included USB cable with a 5V/1A adapter. Plug into the micro USB port; fully charging takes about 2-3 hours.

Why is the phone not turning on?

First, check if the battery is charged. Press and hold the power button for at least 5-10 seconds. If still off, try removing and reinserting the battery. If the issue persists, the battery may need replacement.

How do I adjust the volume and ringtone?

Use the side volume keys during a call or in standby to adjust the earpiece and ringtone volume. For ringtone settings, go to Menu > Settings > Sound Profiles, choose a profile, and select the desired ringtone from the list.

How to use the FM radio without earphones?

The FM radio requires earphones to act as an antenna. Plug in the earphones, then go to Menu > FM Radio. Press Play to listen. The radio will work through the speakerphone even if earphones are used as antenna.

Why can't I hear the caller or they can't hear me?

Check the volume: press the side volume keys to increase. Ensure the microphone is not blocked by a case or debris. If using a headset, ensure it's properly connected. If the issue persists, reboot the phone.

What to do if the screen is unresponsive or frozen?

Perform a soft reset by removing the battery for 10 seconds, then reinsert and power on. If the problem continues, try a factory reset (Menu > Settings > Reset > Restore Defaults). Note: this erases user data.

Can I use this phone with modern 4G/5G networks?
