I love mobile phones. My first mobile phone is Samsung S4. Since then, I have used Xiaomi Mi2, Honor 7, Huawei Mate 9 and Huawei Mate 20 Pro. Similarly, I also love to write articles about mobile phones.

  1. This is a nice guide. I have a question. If I added the 4G MODEM in this laptop, would the card slot have the necessary contacts for the SIM card? If not, can that piece also be purchased?
    This is a Christmas present for a friend. I know he’ll love it the way it exists, but I know he’ll love it more if I can give him cell capabilities.
    Thank you,
