I bought it 2 months ago. I had bought this model before in the past, but this time the Greek font it has is terribly poorly designed. I don't know who did the translation!!! I have only seen such bad font and incomprehensible translation on some Chinese phones. If someone gave me this phone (without knowing it's a NOKIA), I would tell them it's a third-rate Chinese phone. Even the plastic they use on the phone is very fake. I feel like I have a fake Chinese phone with the name NOKIA printed on it!!!! They have really ruined the quality at NOKIA.

Other than that, the battery lasts and it does its job as a phone only for calls. I had the older (exact same model) for 5 years and it fell dozens of times and nothing happened to it. Now I gave it to someone else and got a new phone only because the numbers on the buttons had worn off due to heavy use and some buttons didn't make good contact (logical after 5 years of use). I don't see the new phone surviving falls!!!!

At least it has a cheap price....

Purchased today, January 27, 2021, for €23 for military use, as a camera-less mobile. It is a dual-SIM device, meaning it can take two SIM cards (two numbers). I got it in black.
Simple, lightweight, and compact packaging. As soon as I unboxed it, I inserted my SIM card and activated it. It immediately turned on, I set the time, and it was ready for calls. The battery had power. You don't need to charge it all day with this unboxing. That used to be the case with old mobiles (20 years ago) that had NiCD, NiMH batteries. Nowadays, it's a myth. Mobiles and portable devices today have lithium-ion (Li-ion) batteries and can function immediately even with a low battery level, without affecting their lifespan and reliability.
If your contacts are stored on your SIM card and not in the memory of your previous mobile, they will be transferred as they are to your new mobile.
Very easy and practical to use for what you need it for - a simple mobile for calls. Suitable for the elderly (although I'm not sure if they can see the small letters), for soldiers on duty, for people who want an affordable basic mobile phone for essential tasks, for those who prefer a physical keyboard over touch-screen mobiles, or for those detoxing from technology to reduce stress and social media usage.
My mother has the same Nokia 105 in blue for a year now, and it has proven to be reliable and fully functional for her simple needs. It has even survived being dropped without any damage. That's why I also bought the same one for the military.
It only operates on 2G networks, which is a downside. It could have supported 4G networks so that it could still function in the future when mobile network companies abandon 2G. However, 2G has been supported for many years and still works. But if companies discontinue it, mobiles that only support 2G will become useless.
It takes a large SIM card, so that's another downside. If you had an iPhone or a touch-screen mobile with a smaller Nano or Micro SIM, you would need to buy a SIM adapter kit to convert it to the larger size to fit the mobile.
In addition to calls and SMS, it has an alarm clock, calculator, FM radio (requires headphones with the standard 3.5mm jack), flashlight, micro-USB port for charging, so it is compatible with various chargers and power banks with micro-USB cables. As for games, it has the classic Snake game and six others, which are trial versions that can be played five times before requiring payment. The battery capacity is 800mAh.
In the settings menu, you can set a security code for the mobile itself, in addition to the SIM PIN, so that if it gets stolen and locked, no one can access your sent SMS or contacts even if they remove the SIM card. The default security code is 12345, but you can change it and activate it when you open your mobile.
The flashlight is quite useful, but it is not very powerful. It is suitable for basic tasks.
The Nokia AC 100-240V charger is of good quality, providing 5V@500mAh with a micro-USB, and it can also charge a small rechargeable flashlight that I have. So, in the military, you have one charger for both devices.
According to Nokia, the standby autonomy is 619 hours and the talk time is 14 hours, but in practice it is less and could be better. It is economical because with about 20 euros, previously before smartphones, in the era of Nokia 3310, you would have to spend much more to get a mobile phone with similar capabilities. Of course, the evolution of technology (smartphones) helped with this, but even today, for what you need it for, such a simple mobile phone does its job just fine. I will use it during my military service and evaluate it later.

Update March 18, 2022: It still works perfectly. I used it for the first month in the army and then switched back to my smartphone. The Nokia BL-5CB battery fits perfectly with a Chinese portable radio and lasts for hours of music without charging, unlike the low-quality battery that the radio had.
