First of all, I would say that 90% of the "bad" ratings, on here, are from first-timers who don't understand how it all works and they were either impatient or ignorant of how to proceed before/during/after the unlock or during the waiting period.
My receipt said it could take 2-5 "business" days, so I will wait 2 to 5 "business" days before getting concerned.
Not every phone takes the same amount of time to unlock. One might take 2 hours, one might take SEVERAL days, it's just the way it is UNLESS you want to go somewhere else and pay more for faster service.
If you look at all the sites, you will see that more money makes processing faster, it's just how it is.
Sending texts and unlocking phones have NOTHING to do with one another. "After" you unlock the phone, you HAVE to set a "new" APN so you can send SMS/MMS correctly. I've seen people blame cellunlocker.net for their own lack of understanding of, well, everything to do with the phone and the situation and it's not fair to the company.
I've bought, over the years, maybe 5 or 6 unlocks from them and never had any real issues with them. I go through phones, pretty rapidly, so I've got a history with these people and I know not every situation is going to be the same.
READ THE RECEIPT. It's going to be your guide to sanity with this process. Read it ALL, especially the part where it says "days to complete" and you won't get so wound up.
Now, in all fairness, I will take note of the other side of the situation. The phone service, associated with this company, it kind of "sucks" because you're put on hold forever sometimes.
You don't always get emails back fast when you email support and sometimes this company's website (like today) goes down for a period of time.
Like I said, I've done this SEVERAL times with this company, and always seem to have a decent experience for ONE reason, I understand the rules.
If you're impatient or paranoid which, let's be honest, there are a LOT of you out there who are both, you're not going to have a good experience with this company.
Bottom Line: Yes, I would recommend this to a friend
