Texted - Pain in the English
https://painintheenglish.com/case/3896So, the obvious answer, if we agree that text is a verb, is that the past tense is 'texted' (pronounced tex-ted) just like: I called you last night (called - not call) or: anyone who thinks the past tense of text is text should be tested (tess-ted) to see if they can speak English properly.
