I can't verify my phone, i'd try it for 3 days

 

I choose my phone no. , save it.

Setting will send me the Code no. to my phone , but nothing , no massage came in.  So i change to send it by telegram. Result came out the same, nothing came in (No massage)  I'd try it for 3 days and can't verify my phone, then i can't put the money in to the Web for the indicator in want to buy.   How can I verify my phone?
