Invalid SIM number when trying to activate SIM

I tried activating my new SIM card. But when I enter the number of the SIM, I can’t proceed the activation process, because of the error message “invalid SIM number”. I checked the number 3 times already, but it always displays this error message. I am posting this here because I haven’t found any direct support contact. Any suggestions?

Is it 20 digits and begins with 894450? ie:


Did you buy it from Hologram? you can also try email hologram at I have found them to be very responsive.

Hey, there was a batch of SIMs that got left out of our database but it should be resolved now. Give this another shot and see how it goes. Sorry for the trouble

Works now, thanks for the quick response.
