What to know before buying

Listing details to confirm

Listing details are contradictory or unconfirmed: the title and specifications give a 5-inch, 800x480 screen, while other listing copy describes a 1.8-inch QVGA display. Battery capacity is listed as 800mAh in the title and details but 1000mAh elsewhere. Single SIM and Dual SIM claims conflict, as do the UK network compatibility claims and statements about supported GSM networks. The charging dock and USB-C charging are advertised, while the stated box list instead names a Micro USB charger. Confirm the selected listing and required SIM/network compatibility before buying.

Who is it for?

A good fit for

Older users or anyone who prefers large physical buttons for basic calls and texts.
Buyers who want an SOS function and a charging dock, and have verified that their SIM works with this 2G handset.

Less suited to

Anyone needing mobile data, apps or a 3G/4G connection.
Buyers who need confirmed dual-SIM operation, a particular display size or USB-C charging without checking the listing first.

Customer feedback highlights build quality, readable large numbers and suitability for older users. Functionality feedback is mixed, including a reported SIM compatibility issue, while opinions on value also vary. Those concerns matter for this 2G handset because buyers should confirm provider compatibility and treat the inconsistent SIM and network claims cautiously. The overall rating distribution is mostly positive but includes a noticeable one-star share, so it does not establish that every buyer will have a trouble-free experience.

Positive themes

Customers describe the phone as well-built and suitable for older people.
Customers praise the large, easy-to-see numbers and clear enlarged menu text.

Negative themes

Functionality feedback includes a reported SIM compatibility problem.

Mixed feedback

Opinions on value for money are mixed.

Frequently asked questions

Does this phone support mobile internet?

The listing specifies 2G and describes calls and texts without internet. It is not presented as a mobile data phone.

Will it work with my SIM?

The listing claims it is unlocked but also names supported UK networks and exclusions, and customer feedback includes a SIM compatibility concern. Check that your provider supports this handset's 2G GSM service and the required SIM format.

What screen size does it have?

The specifications and title state 5, while other listing copy says 1.8 inches. The screen size is contradictory in the supplied listing, so confirm it before purchase.
