About the TCL OneTouch 4021

The TCL OneTouch 4021 is a deliberately old-fashioned bar phone: physical keypad, 1.77-inch colour screen, and a job list that starts and ends with calls and texts. It weighs just 76g and is small enough to disappear into a coat pocket, and because the 1,030mAh battery only has to power a tiny display, TCL quotes standby measured in days rather than hours. That endurance, plus a dual-SIM tray and an FM radio, is the whole appeal. Everything else is minimal. There is 4MB of internal memory with a microSD slot for music, a token 0.08MP camera that is best ignored, and Bluetooth 2.1 rather than anything modern. The important limitation for UK buyers is connectivity: this is a 2G and 3G handset, and with UK operators having switched off their 3G networks it falls back to 2G for calls and texts. It is a sensible festival, travel or emergency backup phone, and a straightforward first phone for a child, but it is not a phone for anyone who needs data.

Frequently asked questions

Is the TCL OneTouch 4021 worth buying?
It is worth buying as a simple backup or second phone rather than a main one. You get long standby from the 1,030mAh battery, a pocketable 76g body and dual SIM support, but with 2G and 3G connectivity only, 4MB of storage and a 1.77-inch screen it cannot do anything beyond calls, texts and radio.
Does the TCL OneTouch 4021 work on UK networks?
It supports GSM 850/900/1800/1900 and 3G on 2100MHz, so it works for calls and texts on UK networks. Because UK operators have retired their 3G networks, in practice it will run on 2G, and it has no 4G or 5G, so mobile data is effectively off the table.
How long does the TCL OneTouch 4021 battery last?
TCL quotes up to 324 hours of standby, around 13 days, and roughly 391 minutes of talk time on 2G from the 1,030mAh battery. Real-world results depend on signal strength, but a full week between charges is realistic for light use, which is why phones like this are popular as emergency spares.
Does the TCL OneTouch 4021 have a camera?
It has a 0.08MP fixed-focus rear camera with no flash, recording video at 176x144 resolution. It exists to tick a box rather than to take usable photos, so treat this as a phone without a camera.
Can you use two SIM cards in the TCL OneTouch 4021?
Yes. It takes two micro-SIM cards in dual standby mode, so you can keep a personal and a work number, or a UK and a travel SIM, on one handset. Only one SIM is active on a call at a time.
Is the TCL OneTouch 4021 a good phone for a child or an older relative?
It suits both cases well, because the keypad and 1.77-inch menu-driven interface are simple and there is no browsing or app store to worry about. A microSD card up to 32GB adds space for music, and with no apps or browser there is very little to go wrong. If a bigger screen and a louder earpiece matter more, a flip-style handset is worth considering.
