Gitzo loan doesn't have to be bound with the mobile phone number, but it should be no problem to have money in the bank card every month.
You'd better contact their customer service, in case I can't contact you in the future, for example, if you fail to deduct the fee, there will be a lot of liquidated damages for one day. You can go to Shenyang Zhonghui. Their service is very good, reminding you of the repayment date every month, which saves a lot of unnecessary trouble. Hope to adopt.
