Sending txt SMS via internet to Polish phones

I want to send some text messages to some friends I made whilst i was in Poland. Does anybody know any english language ones?

I used to use wirtuana bramki sms but that no longer seems to work for me.

Try cbfsms.com - I don't know if it'll work abroad but I use it occasionally when I've run out of credit (in the UK though)

not for all networks but it usually worked when i was in
poland (www).text.plusgsm.pl/sms/

text.plusgsm.pl/sms/

I use this one as well from the USA and it works!

I just send texts from my phone (US Cellular) from US to Poland, but can't get any from Poland. I tried "Sprint" phones, and other local ones here, but they can't text overseas.

that redirects me to bramka sms

can someone give me step by step instructions on how to do it?
