As far as I am aware, for sim only deals Tmobile no longer offer unlimited landlines booster, but instead they now do a booster of 5000 landline minutes. On their 18 and 24 month contracts I believe it's still available.
This appears to be true, *BUT* what members need to remember is that SIM only deals are often not the best way to go.
There are plenty of options for getting unlimited landlines on T-Mobile's
pay monthly plans: indeed if you get a contract with 300 minutes or more, you get a *free* Unlimited Booster of your choice, which includes the unlimited landline Booster.
There are comparatively few cashback options with SIM only plans, but on pay monthly plans including a handset there are far more lucrative choices available.
I myself got such a deal through
www.mobiles.co.uk only 6 month's ago. The cashback from mobiles very nearly pays all my costs, and if Topcashback pay out in addition, I practically have a free handset, free 300 X-net minutes and 500 SMS per month for the 18 month duration, AND free Unlimited landlines as well.
I defy anybody to get full cashback on a SIM only deal !
I am afraid that members who don't do thorough research often fall prey to the belief that SIM only plans are the cheapest, whereas the facts are that contracts with handsets, bought through reputable cashback providers, give far better value IMO.
