[Q] Using the Inspire 4G overseas after SIM/IMEI unlock.

---

Hope you guys can help me.

I will like to buy the Inspire 4G thru amazon and plan to use it in Costa Rica, where we use the same 2G and 3G bands as AT&T (850). Nevertheless I’m not sure if after the SIM/IMEI unlock, it will work with a Costa Rican SIM card? It is very common for us to buy unlocked At&t or T-Mobile phones and use them in Costa Rica.. but I have my concerns.

Last December I bought a Prepaid AT&T Phone (Samsung A107) on a trip to the US, but after doing a SIM/IMEI unlock, the Prepaid phone didn’t recognized my Costa Rican SIM card. And even before that, while still been in the US, I was not even able to use the AT&T SIM card on my unlocked Touch Pro2 (EUR version).

My worst fear is that AT&T is doing some sort of “Hard Sim Lock” to their phones.. and I will kill myself for buying an expensive paperweight.

Your thoughts and comments will be highly appreciated.

Hi, I can't 100% answer your question but I do know why your SIM cards weren't interchangeable. We lock all PUK codes on all prepaid SIM cards to where you can only use that SIM on that phone. If you would've gotten a "regular" SIM you could've used it on another carriers phone. As to why the non AT&T SIM didn't work maybe they scammed you and it never got unlocked.

Thanks for your explanation. So basically and after reading other posts regarding unlocking this phone, the Inspire 4G should work overseas without any inconveniences, after inserting the SIM/IMEI unlock code that you buy from any “respected” and “trusted” site (and as long as the 3G Band is 850) ?

I was going to buy the unlocked Desire HD (Eur Version), but regretfully it wouldn’t work with any Latam 3G Band (as it happened with my Touch Pro2, that only works with 3G band 2100+900).

I got an Inspire 4G on Monday, unlocked it, and my existing SIM card from another country (also in latam) worked right away. Been using it since then both in the US and back home.

So unless there is some lock on the SIM card itself, it should work fine, I think.

That’s the answer I was looking for!! You made my day. To be honest, I want to change from Winmo to Android so badly… that this phone seems to be the right deal.

Quick question just before going to amazon and start my order: Which system did you used to get the Unlock code? I have read in other forums, that some folks have been using htcimeiunlock with excellent results (I’m not related to that company by the way). I just like to hear a second opinion.

And once again..Thank you so much for your assistance!!

Got my phone unlocked

Hey
I'm from Venezuela, and I unlocked my HTC Inspire 4G from AT&T at unlockusa.com. I chose them because they're top-rated sellers at eBay and seemed trustworthy. I got my unlock code within 5 minutes, and everything worked as expected.

Hope you enjoy your new phone!

Yes, I used htcimeiunlock.com. Got my unlock code in a few minutes with no problems whatsoever.

Hmm 2 new members and advertising new site?

The AT&T Inspire only has North American UMTS radios 850 and 1900 Mhz. It lacks the 2100 radio necessary for 3 and 4G in Europe.

The phone will work on Europe's 2G Edge network. HTC should have put the 2100 Mhz radio in the Inspire but they didn't. This is the real gripe I have with this phone.

Doesn't the desire hd cover the european market with 2100? I suppose if you are traveling it is an issue but otherwise I see no reason for att to be adding something to this phone that already exists in one of its twins. Also it is not marketed as a "world" phone by at&t either.
