This is a Samsung Galaxy A20 SC-02M, a SIM-free model sold by docomo, that was used as a dedicated device for "video viewing, searching, and phone calls"! As you can see, the exterior has many noticeable scratches on the frame... The back is slightly warped, but the 5.8-inch LCD screen is relatively clean, and this is a piece that highlights the GALAXY's unique "compact and simple design" ❣ ʕ•̀ω•́ʔ✧ 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 and volume, Wi-Fi, tethering, etc., are all working normally, and the battery is also very good... It lasts from morning to evening with normal use ❣ (^O^)v The best part is that it's compatible with most carriers, including "docomo," "au," and "SoftBank," as well as "mineo" with unlimited low-speed data for 900 yen, "povo" with a free basic plan and optional add-ons, "LINEMO" with 900 yen refunded for 6 months, and "Rakuten Mobile" with unlimited calls and data for 2980 yen (excluding tax) ❣ (*•̀.̫•́✧ However, this model doesn't catch these signals just by inserting a SIM card, so for those who are not confident in setting it up, I can set up your preferred carrier's APN after "initialization," update the Google Play Store, and then you can enter your Google account, etc., and I can hand it over to you in a ready-to-use state ❣ (^^)d This SIM-free device with no remaining balance is equipped with the latest OS "android 11" and has "RAM 3GB/ROM 32GB" of storage. This docomo-approved model, I believe, can still be used on the front lines ➰ (^-^) 【Request to Customers!】 We accept "cancellation requests" due to unavoidable reasons from the customer's perspective, but in that case, the return shipping fee (about 180 yen for Click Post or Smart Letter) will be borne by the customer...
