can you gets these sim cards for free

Not for free exactly but the cost of them includes the air time. So you pay a £1 and they give you £10 air time.

Plus if you know someone else on EM just enter their number when signing up & you both get an extra fiver credit.

I paid £1 and got £19.66 free credit when I orderd my sim card.

i paid £1 & got £26.66

I paid £5 (for 5) and got nearly £60 credit on my main sim, by the time some people had used my number as a referal

Sim 1 - £1 + £10 + £5 Referal from original referee + £20 referal from sims 2,3,4,5 = £36

Sim 2 - £1 + £10 + £5 Referal from sim 1 = £16

Sim 3 - £1 + £10 + £5 Referal from sim 1 = £16

Sim 4 - £1 + £10 + £5 Referal from sim 1 = £16

Sim 5 - £1 + £10 + £5 Referal from sim 1 = £16

Grand total over 5 sims = £100

Luvvly jubbly.
