Can I sign the contract online completely by mobile phone? Don't you need to send information by fax?

Electronic contracts can be signed entirely by mobile phones.

Electronic contracts have the same legal effect as paper contracts, but in order to meet the relevant legal requirements, it is very complicated, so the third-party electronic signing platform is generally chosen.

The specific signing process is roughly as follows:

1. Select a reliable third-party electronic signing platform, register and authenticate (to prove that you are you in the network environment). You can make your electronic signature and the company's electronic official seal through the platform.

2. upload the document to be signed, fill in the customer's name and mobile phone number and send it (the signing order of both parties can be customized)

3. The customer receives the short message containing the signing link on the mobile phone short message, clicks the link to authenticate according to the page prompts, and generates a handwritten electronic signature and signature.

when both parties sign it, it means that the whole contract is signed.
