Checking if there are no numbers from cellular services
Have a look whether you can extract the code into a function. It then may look like this.

def has_no_numbers():
  if use_verizon_sms:
    return Api.check_avalible_credits()

  if use_verizon:
    return buy_verizon_number()

  if check_count_numbers()
    return True

  raise Exception("THERE IS NO AVAILABLE NUMBERS")
