I registered to SP129 and I was asked to proceed in spotify.globe.com.ph and entered my 11 digit mobile number. When I submitted the form it says "Not a valid mobile number" but I'm sure that it's correct as I tried it multiple times. I don't encounter this problem before when I activating my SP129 promo so I don't know what to do. I tried it on my PC and mobile browser all of which is not working. Please help me on this!
