I have been using the Nokia 150 (2023) as my daily driver for a month now. The purpose of buying it was to disconnect from the Grid (Internet/Social Media/etc.). I wanted a phone that would not have internet connectivity in its design.
As a simple everyday phone, it is very good. It has a calendar, camera, voice recorder, calculator, and its battery lasts exactly one week with heavy call usage. I charge it every Sunday. The screen is bright and the colors are very good. Its resolution is satisfactory, without noticeable pixelation. It gives a new retro feeling.
Now, some details that someone should know before buying it: It has a limitation on the number of characters that can be entered for a name (16 characters). It is not enough for many names if you are used to writing full names like I do. It does not have synchronization with Android, nor does it import from a vcf file. You can only import from the SIM, or else you have to manually re-enter all your contacts, which took me an afternoon at first. On the other hand, the most serious issue is that it does not allow you to enter more than one number for each name. Also, searching for names is case sensitive, so if you search for "George", it will not find "Γεώργος Τάδε". This means that the best strategy is to enter names in all lowercase letters to make the search work without many movements. (To search in contacts, you do the following: As you open the contacts, you start typing the name you are looking for. By default, the phone puts you in lowercase Greek, which is why it is convenient to write the names in all lowercase Greek).
Apart from these peculiarities, it has a powerful flashlight that also works as a flash in photos, contrary to what the reviews on the internet say. You just have to adjust it first. Additionally, its radio is very good and works without handsfree. The loudspeaker is not at the level of expensive smartphones, but it is very good for its size. With its alarm, it is impossible for everyone in the house not to wake up. It has a call and message log, and it also records calls. Its camera is nothing special, but it is sufficient for taking pictures of codes, a supermarket list, and other practical things. Do not expect to go on a honeymoon and take great photos or videos with it.
Since I bought it as soon as it was released, its firmware has some bugs, such as distortion of the letter "Ε" in the word "Επιλογ." momentarily before locking (you don't even notice it and it's not a problem, I just mention it). Or, the ringtone returns to the default Nokia tone if you remove the battery. It does not have VoLTE (only GSM), it does not have VoWiFI, so call quality is at the best levels that 2G can provide, but in places where there is 4G and not 2G, it will have interruptions. Fortunately, these issues are rare (mainly, I have encountered them in buildings where they have installed 4G repeaters but do not transmit the 2G spectrum).
Overall, for someone who does not want to leave a digital footprint but wants to have a telephone experience similar to what we had in 2004, it is an excellent device, with a sturdy construction and very beautiful. It is not the Nokia quality we remember, but for a non-mainstream device, it comes close. It is worth its money.
