Be cautious about wasting your money on TempNumber. I topped up $5 and used $2.9 to buy a number for registering a Google account. After binding my credit card to Google Play and purchasing an app, Google disabled my account for violating policies. I appealed several times, but Google claimed that I used an abnormal number that cannot be restored, even not accepting I change to a new number. As a result, I not only lost $5 for topping up, but also $20 for the purchased app on Google Play. TempNumber is bound to my Google account, so now I lost access to TempNumber too. There's no way to recover these losses. If you contact customer service, they will only tell you that they do not promise any consequences from the number. The number you use will be used by countless others, which will eventually lead to all those account being banned together. You can't even find an option in TempNumber to refund the remaining money.
