Spark's FREE 10gb Socialiser is back for the summer. They usually have it every year, and so I thought I'd try it this time. Spark doesn't seem to have announced it yet, but the offer is now active.
The link gives you info regarding the normal and PAID Socialiser, but this one is free and works the same, plus x10 the data! Be sure to text the code ADD SOCIAL to 258.
Free on MOST pay monthly plans.
