Reducing the MTU to 576 bytes is likely to help.  That was commonly done in the days of analogue modems, when such low speeds were normal.

I'm fortunate enough to live somewhere where the local ISPs don't limit your data transfer, even on the budget subscriptions.  Roughly €25 will buy you 500Kbps mobile service for three months, and you can use that 500Kbps as much as you like.  And that is with the lowest population density in Europe, so the per capita cost of covering the country in cell towers is obviously no excuse.
