Thank you for your email, iPhones<sic> are locked and are not being unlocked.

This is the heart-breaking response I received last week when I asked whether I can use a Telcel micro-SIM on my iPhone 4S when in Mexico.

It’s now even more evident that Sprint does not yet have it’s <deleted> together when it comes to these kind of details regarding their iPhone 4S.

I went to a Telcel store today. I patiently stood in line for half an hour. I gambled all of $150 pesos (about $11.50 USD in today’s rate) on a prepaid “Amigo” micro-SIM card. Popped it in and voilà! It works: I have my own local phone number.

So here it is: if you bought an early Sprint iPhone 4S, I can guarantee that at least for me:

  1. AT&T micro-SIM did not work.
  2. Telcel (Mexico) micro-SIM works like a charm.

This agrees with other reports I’ve read online. I’d love to hear about your experiences, as YMMV.

  1. here is the story…. i bought an i phone 4s from a guy is has a clean/good ESN here in the US(I checked). He said he bought it before 11/11/11 but it has ios 5.0.1

    if this is true and he bought it before 11/11/11 but it has 5.0.1….. will I still be able to use it when i travel to Mexico and use a prepaid Telcel sim card from Mexico???

    is it also true for BAD ESN iphone 4s….. Can a Bad ESN iphone 4s bought before 11/11/11 be use with a prepaid Telcel sim card from Mexico??? does it matter if its on 5.0.1 or 5.0???

    1. Not sure what ESN means, but if the iPhone is a Sprint iPhone, then it will most likely work even with iOS 5.0.1. It works for me, that’s for sure. AT&T or Verizon will not work.

  2. Thank you for the reply!

    Good esn means that its not stolen an you will be able to re-activate with sprint.

    Bad esn its the opossite!

    Did you ever tried to put a at&t sim or T-mobile? What was the result if you did? Did the carrier option stayed on? Do you know or do you think that it can be use with any pre-paid in the world? *Except USA!!

    1. I tried an AT&T SIM right after I got the phone and it did not work for me but YMMV. I have not tried T-Mobile.

      To me, it seems like it will work with any prepaid micro-SIM in the world except US T-Mobile and AT&T. I know for a fact that it will work in Telcel (Mexico) and Cellcom (Israel) and I read that Rogers (Canada) works.
