Root HTC EVO Design 4G - All Carriers - Root guide

SquirrelNoises said:
Yes, I did. I have popped the battery out, reseated the SIM card, and rebooted several times too.

Also, when I go into the About Phone > Network menu, it says "Operator Name: Sprint". Maybe I need to change something in my settings?

I believe you would need to call Sprint and get them to guide you in unlocking the carrier on the phone. The HTC EVO Design 4G is a world phone and thus supports pretty much any network; however, in the U.S. it is locked to using Sprint's CDMA network. Rooting and unlocking the boot-loader are not the same as unlocking the carrier/radio.

You can however try this and see if it'll work:
Open Settings and go to "Call." In there tap "Preferred Network" and change it to "GSM/UMTS Mode." If it prompts you on whether to do GSM or UMTS, select GSM. (Although, UMTS might work.)

I had once put a T-Mobile card in mine (albeit T-Mobile prepaid) and the phone didn't complain about it being in the U.S. but couldn't read the SIM Card for some reason.

The reason they say T-Mobile's 4G won't work with this phone is that Sprint uses WiMax for 4G and T-Mobile uses HSPA+.

If you manage to find a way to get them to do it, let us know EXACTLY what you said and who you talked to. I literally tried to do this today and they told me they would not (not could not, WOULD NOT). **** Sprint, and I hate this piece of shit phone.

Oh wow... I have the Boost Mobile version of the phone which has the Preferred Network setting. I wouldn't have ever imagined that not being in the Sprint version of the phone, that is quite interesting. In that case I'm not sure what to tell you as I'm not sure of any other place in the settings to tell the phone to use a different network by default. Your only option may very well be to somehow convince Sprint to not only let you unlock the phone from them, but guide you in doing so. Which from the post after yours, quoted below, it doesn't seem like they will. Although, depending on how long you were with them, they may be willing to. I know that T-Mobile allows customers who have had their service for 2 years(the contract terms) to unlock the phone for free, but I'm unsure of Sprint's policy on it.

I'm really sorry to hear that. All of the carriers do this, but it's quite ridiculous of the companies to lock the phones to only their network. Customers should want to use them because of their prices and service, not because of their phones! If you were with them for a while, you may want to try what I said above and see if they'll do it since you were a loyal customer for a decent amount of time.

Would it work if I rooted it instead of just unlocking it?

Well, the phone is supposed to be locked to CDMA while in the United States. Only foreign SIM cards are supposed to be usable. In example, if I select "Preferred Network" and then "GSM/UMTS Mode" it gives me a pop-up window that says "GSM/UMTS Mode not supported in the U.S. Only foreign SIM card usable in device. Your device will switch to CDMA mode now."
Oddly when I put a Prepaid T-Mobile SIM card into the phone and selected that, it wouldn't tell me that and did indeed switch; however for some reason, maybe the locking or maybe as it was for a prepaid T-Mobile phone's SIM card, couldn't read the card properly.

With this said, and again stressing everything says that only foreign SIM cards are supported by default, I don't think anything less of getting Sprint to unlock it will help. Especially since unlocking the boot-loader and/or rooting are unrelated to unlocking the carrier lock.
