The phone is worth £29.99 for anyone wondering. Tesco sells it with £10 of free credit included on PAYG.
If you get it on PAYM, it's £7.50/mo for a 24 month contract. They also do the Doro 6820 and Nokia 2660 Flip at the same monthly prices. They also do a Moto e14 at £8/mo which is just 50p more for a decent smartphone. I don't mean to advertise, I'm just sharing for context.
A lot of people will buy the Nokia 110 4G for resale especially with that free £10 voucher included. Other than that, we don't sell it much because customers prefer the IMO Dash 4G (Tesco's in-house cheap button phone) or the Doro 6820 instead. Nokias are not as easy to use and have a slightly higher return rate for that reason.
