would be nice to have this option not really intersted in internet on my phone
The £5 goodybag lab, or is it lab goodybag, will probably work for you. For a total 1 month cost of £25, you could send 2,000 texts or use 1,000 minutes or any combination.
giffgaff can't match every single tarriff ever invented.
If you prefer the ASDA deal get an ASDA sim and buy it then.
Giffgaff offers what it does, unlimited everything for £30 including alot of things the asda deal doesnt include. ie free 0800 calls free giffgaff to giffgaff and free data. Also, when it says unlimited it truly means that, unlike ASDA which will have a FUP.
