This is an "AQUOS R SHV39 [OS 9/64GB] SIM-free" phone, originally sold by au, that has been used as a dedicated device for "video viewing, searching, and phone calls"! As you can see, the exterior has some scratches and discoloration on the frame, but the 5.3-inch LCD screen is in relatively good condition, and this item showcases the AQUOS's characteristic sturdy and simple design (*^^*) As far as functionality is concerned, as far as I've checked, the LCD touch, SIM communication/calls, various buttons, screen display, good sound quality/volume, Wi-Fi, tethering, etc., are all working fine. The battery life is appropriate for its age, but it lasts from morning to evening with normal standby use (^O^)v The best part is that it's compatible with most carriers, including "docomo," "au," and "SoftBank," as well as "mineo" (unlimited low-speed data for 900 yen), "povo" (basic fee is free, with add-ons), "LINEMO" (900 yen for 6 months of service), and "Rakuten Mobile" (unlimited calls & data for 2980 yen, excluding tax). You can use it to its full potential! [However, docomo lines can communicate but not make calls!] (゜∀゜) However, this model doesn't catch these signals just by inserting a SIM card. For those who are not confident in setting it up, I can set up your preferred carrier's APN after "initialization" and update the Google Play Store. Then, you can enter your Google account, etc., and it will be ready to use. Please let me know the "carrier name (docomo, etc.)" before shipping. (If you don't want this, I will ship it after initialization!) (^^)d This SIM-free phone has no remaining balance and is equipped with "RAM 4GB/ROM 64GB" and "Android 9" OS. This au-approved model can still be used on the front lines, I believe ( ゜∀゜)o彡° [Request to Customers!] We will accept "cancellation requests" due to unavoidable reasons from the customer's perspective, but the return shipping costs (about 180 yen for Click Post or Smart Letter) will be the customer's responsibility. Also, customers using convenience store payments, please let us know the "exact payment date and time." m(_ _)m
