Kannel: Open-Source WAP and SMS Gateway

Weird to see this mentioned now since I just mentioned it a few comments ago. But if you just have an old device and need a WAP 1.0 gateway you can use this: https://nbpfan.bs0dd.net/index.php?lang=eng&page=wap%2Fmain

Here's a pic of my first cellphone loading it earlier this year: https://files.catbox.moe/cmi78w.jpeg

Newer mid-2000's phones are WAP 2.0 and don't need a gateway (they also mostly support j2me, so this is the way to have a mostly usable browser with opera mini, otherwise pretty much all TLS sites but m.google.com will fail)

EDIT: I am on t-mobile and they shut down their WAP gateway ages ago with the exception of MMS.

Is T-Mobile's 2G network still alive? I thought it was shut down months ago.

On that note, are there any 4G phones that support WAP?

Edit: I saw your comment at https://news.ycombinator.com/item?id=42434295 Using an eUICC is a neat hack! I'll have to try that.

Yeah, they were going to shut down but it doesn't cost them anything to keep it running and avoids a lot of liability on devices that can't do voLTE/voNR (for 911/government/legacy). I would imagine it's also a small revenue stream from international roamers on their network.

They had good spectrum planning so it fits in their guard bands in 1900mhz without fucking up LTE or NR deployments. That or since Neville retired (the CTO for most of their history) they stopped beating deadlines.
