Celkon C10 review
This phone is essentially dead. If you live in a region with no 2G coverage, you cannot use it at all. If you do live in a place with 2G, modern smartphones are available for the same or less money and will work for years longer. The only valid reason to own one is pure nostalgia or a museum.

This review is written with AI assistance from Celkon’s published specifications and public benchmark data for the Celkon C10, and the rating is spec-based. GoSolo does not physically test devices; where we estimate real-world behaviour such as battery life or charge time, we say so. How we rate phones.
Overview
The Celkon C10 is a 2011 feature phone with a tiny 1.8-inch screen, dual SIM, and a removable 800 mAh battery that struggles for anything beyond basic calls and texts. It is essentially obsolete today unless you need a dirt-cheap backup or have no other option in a place where 2G still works.
What you're actually getting
This is a 2011 feature phone, not a smartphone. It makes calls and texts, plays audio and video files from a microSDHC card, picks up FM radio, and has a camera. Anything beyond that—apps, mobile browsing, email, or instant messaging—does not exist here. If you bought this new thirteen years ago, you got a basic mobile for emerging markets or as a backup. Today it is exclusively a piece of tech history or a last resort in places where 2G networks still operate and modern phones are unavailable or unaffordable.
Display and usability
The 1.8-inch screen with 128×160 resolution is genuinely difficult to use. At 114 ppi, individual pixels are visible, and the tiny real estate makes scrolling or reading text a chore. A modern smartwatch has a bigger, sharper display. The 20.5% screen-to-body ratio tells you most of the device is bezel. For a device from 2011 this was acceptable; in 2025 it feels like operating a device with mittens on.
Battery and charging
The removable 800 mAh battery is a relic of an era when non-removable batteries were not yet standard. On paper, it promises up to 150 hours of standby, but in real use with a SIM active and any radio on, expect a full day at best and often less. The 5-hour talk time figure means you cannot rely on this for extended calls. The saving grace is that you can carry a spare battery and swap it without a charger, but you will be swapping often.
Connectivity and usability in 2025
This phone is GSM-only, meaning 2G. In 2024 and beyond, carriers worldwide are shutting down 2G networks. The UK, Australia, and South Korea have already switched them off. The US, Europe, and much of Asia will follow by 2026. Even where 2G still works, you get no 3G or 4G data, so no email, no web, no maps, no nothing beyond calls and SMS. This phone is becoming legally unusable in major markets and is already obsolete everywhere else.
Camera and media
A 0.3-megapixel camera (per the specs) is barely usable for anything and certainly not for anything you would want to keep. Video recording exists but is similarly basic. The saving grace is the microSDHC slot and audio/video player, meaning you can load your own music and video files offline. For someone in an area with no data, that is something. For anyone else, it is a novelty.
Build and physicality
At 81 grams and 14.3 mm thick, the C10 is genuinely light and pocketable. The dual mini-SIM support lets you run two numbers or switch carriers without needing a dual-SIM phone. These are real conveniences, even if everything else is behind by over a decade. The flashlight is a practical touch, though every modern phone has one now.
Who this is for
The Celkon C10 exists now only as a backup for someone in a region where 2G still runs and nothing else is available, or as a collector's piece. If you are shopping in 2025, do not buy this. Even the cheapest modern smartphones cost less, work globally, and do infinitely more. If you somehow already own one, it will stop working within two years as 2G networks disappear. It is a phone from a different era—durable and simple, but utterly outdated.
Verdict
This phone is essentially dead. If you live in a region with no 2G coverage, you cannot use it at all. If you do live in a place with 2G, modern smartphones are available for the same or less money and will work for years longer. The only valid reason to own one is pure nostalgia or a museum.
