Have you ordered a *Boost* tariff? If so, the 2nd SIM card is a free multicard that is included in the tariff.

Hello @Kirankhan9955 ,

welcome to the o2 Community .

If you ordered a Boost tarif then it is as Bumer has explained, a free additional multicard that belongs to that contract.
If you haven’t ordered some form of o2 Mobile Boost, then please check the emails that you will have received for your orders, do these list different phone numbers or order numbers? Because then you’ve got two contracts and if you only want one, then you should see about withdrawing from one of them. For that you can use the following form and then send that to widerruf@cc.o2online.de and of course we’ll be here for any further questions.

Best regards, Sven

I have not ordered boost tariff.

i do see 2 order numbers in my past emails. Also, I received 2 different parcels for delivery of sim. Now, the problem is I dont know know how do i cancel one contract and I won’t know which sim will it be associated to.

 I have ordered o2 Mobile M 25Gb.

after the contract, I see 2 differebt emails for 2 different order numbers. I’m still confused, If I have made 2 contracts or not. 

Hello @Kirankhan9955 ,

you’ve made two different contracts. If you want to withdraw from one of them, then please send in a mail to widerruf@cc.o2online.de. For this you can use one of the pre-made forms or also send in something you wrote on your own, as long as it’s clear that you want to withdraw from the contract and which one you want to cancel. You can also check out this article for some further information:

Kind regards, Sven
