0755 is bank collection or online loan collection?

The collection SMS/phone number at the beginning of 0755 should not belong to the bank, and the online loan platform is more likely. Because banks want to run for collection, they usually call directly with their own service hotline number, and online lending platforms may run for collection through third-party traffic platforms.

Please note that 0755 is the area code of Shenzhen, Guangdong Province, so it may be a dunning call from a loan company located in Shenzhen, Guangdong Province. Of course, it is also possible that the customer lives in Shenzhen, Guangdong, so the loan company uses the area code here.
