The phone factory/ Manufacturer test the function of the phone to make sure it is in good condition. EAST LINE is the China Professional Telephone Manufacturer Supplier. In our telephone factory, after assembling the telephone, in addition to self-checking by employees, it also needs QA sampling test to ensure that the telephone products in the factory perform well. If there is an amount that does not match the test, all rework is required to ensure the eligibility of the product. #telephone #factory #phone #corded #manufacturer #china
