  • Also about:

    Genuinely surprised to hear someone using 2G data, given 3G was phased out as is.

    At least in some countries around Europe, 3G was shutdown rather than 2G. It used up more bandwidth, and most devices can still fallback to 2G, plus at least in Slovakia 2G had superior coverage. Well, still has over 4G/5G.
    Plus there’s a lot of 2G-only IoT devices like electric and gas meters, and those companies are less likely to upgrade than individual customers.

    So far, only Orange plans to shutdown 2G, sometime around 2028. I’ve also seen an idea to keep one single 2G network that would be shared between all 4 carriers, which is an idea I quite like.
    Remember, it’s also a fallback for modern devices when VoLTE/VoWiFi/VoNR doesn’t work.









  • Chinese.

    The projector thing isn’t quite new, actually. Samsung Galaxy Beam did this in 2012. Though that projector was 15 lumens, Unihertz has one with 100 lumen projector. It also has a cooling fan for that, and huge battery that makes it a bit of a brick.

    I myself have Ulefone Armor 24, and I do like the brick form-factor, but I know most people probably wouldn’t.

    These are listed for the Tank 3 Pro: 2G GSM (Bands 2/3/5/8), 3G WCDMA (Bands 1/2/4/5/6/8/19), 3G CDMA2000 (Bands BC0/BC1), 4G FDD-LTE (Bands 1/2/3/4/5/7/8/12/13/17/18/19/20/25/26/28A/28B/66), 4G TDD-LTE (Bands 34/38/39/40/41/42), 5G NR (Bands N1/2/3/5/7/8/12/13/20/25/26/28/38/40/41/77/78)

    You can find band number list on Wikipedia to get the frequency.

    Checking T-Mobile US website, it seems to lack 600MHz for both “extended range” 4G and 5G as well as mmWave 5G support.

    Keep in mind the possible lack of updates with no custom ROMs available. That just sucks, and is usual with such Chinese brands.







  • Yeah, it does that for some VPNs. As well as blocking uploads from Ukraine, which is only given as Something went wrong with CREATE_ALBUM_FAIL. Please try later

    A part of the awesome modern web experience.

    Some VPNs are completely blocked on random websites, Slovakia Swan Mobile (4ka) keeps getting blocked by Google Captcha, Ukrainian Lifecell keeps getting blocked by Cloudflare, Czech T-Mobile keeps getting blocked by Reddit, etc.
