I've seen various offers for this phone .... ranging from cheap initial phone cost with expensive and lengthy monthly outlays ..... complicated cashback schemes ..... or just expensive phone outlay charges.
I think I've found a good middle ground here. The initial phone cost outlay is £199.99 but you can get £35 of that back through Topcashback ..... the contract length is 18 months for only £18 a month ... ok you only get 100 mins / 100 texts but you get unlimited internet which has got to be included with a phone like this.
The total outlay is 18*£18 = £324 + £199 - £35 = £488
Cheapest price I could find for the phone alone is £480
So you get all the calls and internet for free + in theory are able to pay for the phone interest free over 18 months.
