A warm welcome to our Community Forum Madalin110 and sorry to hear you've not received your SIM yet.
I can't find your details so I'm unable to check and I'm unsure whether you've contacted us about the SIM, but can I ask whether this was part of a Oomph bundle? Have you received any details about your SIM at all (apart from the SIM that's not arrived).
Please let us know so we can help.
Thanks,
Lisa
