Learn English – “Didn’t check” vs. “Hadn’t checked”

tensesword-choice

I text-messaged my friend on his cell phone last night and this morning I got a reply saying, "I had saved your number, …but I didn't check my cell until now.."

Is "didn't check until now" okay, or should it be "hadn't checked it until now" ?

Hadn't checked until now would be incorrect, as hadn't checked (or had not checked) is the past perfect tense, meaning he would be saying that something had not yet occurred at a moment in the past. However, now indicates that the point of reference is the present.

I think your primary confusion is the change in tense from had saved (past perfect) to didn't check (simple past). I would actually take issue with the first part and change it to the simple past to match the second half:

I saved your number, ...but didn't check my cell until now

Though I personally would suggest a simple past followed by a present perfect:

I saved your number, ...but haven't checked my cell until now.

But keep in mind that grammar (and spelling... and in some cases coherence) are rarely considered mandatory in text messages.
