Couldn't get SMS verification code from Tinder, even though I had no problem doing so with other apps like WhatsApp etc. Lots of people having the same problem, inexplicably, appears to be some problem with the software. Some have had success installing previous version of Tinder (don't know where to get it though, and not sure it's safe) then updating to new version once they get signed up. I couldn't be bothered though, since you can't filter out single moms and smokers, seems pretty limited.
Tinder customer service was no help whatsoever, told me to check my mobile connection or try again later. Investors be warned, this is a company that does NOT have its act together. So you can find me on POF, which has lots of filters and doesn't even link to your phone number, you can just use the site or app as you please.
