Compare Prices Across Different Sellers

Compare Prices Across Different Sellers

The price of used phones is often variable, dependent on the condition of the device, and sellers determine the price based on its external appearance. Therefore, it's crucial to explore various sources on different websites for reference. Focus on functionalities such as 3G/4G connectivity, display, touch responsiveness, battery life, and more, rather than solely on the device's appearance. Mytour Superstore provides guidance on these aspects below.

Warranty and Return Policies

When dealing with used items, it's crucial to thoroughly examine this aspect. Using pre-owned goods requires mental preparation for unexpected issues during usage, whether software-related, hardware-related, or visible physical damages like scratches, camera functionality, and touchscreen condition. Therefore, warranty and return policies provide peace of mind and future rights for users.

After examining the warranty and return policies, it's advisable to research those who have previously purchased from the seller and evaluate the seller's reliability. Thoroughly understanding the seller can help mitigate risks in transactions and avoid dissatisfaction with purchased devices.

Check IMEI Number and Phone Signal

After selecting the right time to buy a phone, visit the store and choose a desired product. Subsequently, verify the device's IMEI number, as it is a crucial identifier that can reveal the device's origin and authenticity. For Fullbox items, cross-check the IMEI on the device with the one on the product box. To check IMEI, dial *#06# to display the IMEI number.

Check Display and Touch Functionality

This is a crucial step that requires thorough examination, as it directly impacts your future user experience. When dealing with used devices, conduct a Speed Test to assess performance. Due to space limitations, Mytour Superstore introduces methods to test screens for various popular phone brands:

LG: Enter command: 3845#*model#. For example, if you have an LG Optimus G with model F180, input 3845#*180#.
Asus: *#*#4636#*#*
Lenovo: ####1111#
HTC: *#*#3424#*#*
Sony: *#*#7378423#*#*
Samsung: *#0*#
Xiaomi: *#*#64663#*#*

With the provided codes, here are the detailed procedures you need to know:

All Auto Test: Automatically test for Usim card - sim, SD card - memory card, and Earphone functionality.
