How can I claim £10

[Bencent]

Hi

i am new to o2 with my original number how can I claim my £10 credit please?

i was sent  free10 to 21500

but I received this following message 

It looks like this offer isn't for you.

But you can still check out our other treats. Like O2 Rewards, where you can get up to 10% back on your top ups. Use it for extra airtime credit. Or save it for something special. http://s.o2.co.uk/ERyclD

More for you.

Terms apply. To stop texts call 2220

i was ordered this sim at o2 online shop.

You can't have the free £10 if you port in a number.

It's only available to the original O2 number on the supplied sim card.

New Pay As You Go Customers ordering a SIM via
o2.co.uk/freesim or SMS during the Promotional Period will 
receive a promotional Pay As You Go SIM (the "SIM").
The promotion is to claim £10 extra credit. Customers must
activate the SIM by topping up with a minimum of £10 and text
the code 'FREE10' to 21500 within 28 days of ordering the SIM.
Texts must be sent from the SIM and the original mobile number
identified on the SIM pack. Texts sent from mobile numbers that
have been ported onto the SIM do not qualify.
