★★★★★Oct 21, 2026

bấm vào link lại bật ra web tammi rồi mới quay lại app, hơi lòng vòng

★★★★★Oct 21, 2026

trash

★★★★★Oct 21, 2026

Nhiều tính năng thừa, thậm chí còn không hoạt động, cái website lỗi từ 2018 rồi chưa fix. Sắp xếp UI ngu. Cái cần nhất là dark theme thì không có. Rác ngang app cũ :D! Được mỗi cái dùng rất là mượt, hơn app cũ.

★★★★★Oct 21, 2026

bấm vào xem tin nhắn thì ko quay lại màn hình chính đc, phải tắt app mở lại mới đc. Mà ông nào ng QN-ĐN viết cái app này hả? chỉ có QN-ĐN mới xưng ta-mi thôi. Chịu thật đấy. Mang văn hoá vùng miền vào app rồi bắt cả nước xài, bị bắt ép xài luôn đó.

★★★★★Oct 21, 2026

nạp tiền điện thoại xong đợi mãi không thấy tiền vào :((

★★★★★Oct 20, 2026

App ko có mục chặn kết nối Wifi của từng thiết bị đang kết nối với modem
