Care to provide a bit more detail?

A properly unlocked phone should work on any carrier which supports the frequencies the phone was designed to operate on.

I tried 8 different SIM cards from 3 different carriers in Viet Nam including the same carrier I used in this phone before. I also used a working SIM card from a friend's phone. None of them work.

There is no way for Koodo or any cellular provider to "lock" your phone again once it has been unlocked. Once it's unlocked, it's unlocked forever.

Yes, your phone will work with other SIM cards, however, the phone itself must be compatible with the network you intend to use it on. Your unlocked phone may work on Koodo's network, but it may not work on Freedom's (Wind's) because each network uses different frequencies. Simply put of course. lol.

I used my phone in Viet Nam before. The I had a Koodo plan in Canada. Now my phone will not work in Viet Nam. We tried two different companies and 4 SIM cards with no luck

Bob is right.  I bet your old sim cards have expired.  have you tried those sim cards in another phone to see if the sim card works?  Or have you tried a confirmed working sim card from another provider into your phone?


If your phone is indeed locked it would ask for a sim unlock code when you insert a sim card from another provider

I discarded my old SIM cards months ago. My problem is that new SIM cards do not work.

Needless to say, I am disappointed that you have no more comments or suggestions, and that Koodo does not seem to be taking any responsibility for my problems.

OK so I've read through this here and I noticed that you didn't answer what the phone says besides it doesn't work. Does it ask for an unlock code or does it just not connect? Please be specific so we can help you. If it asks for an unlock code I'm not sure what happened. I'd it was already unlocks it's not supposed to ask for another. It might come down to spending the 3-5 dollars or just reenter the lock code you got originally. You got it from Koodo, right? If it just doesn't work, and the same cards work In other phones, then your phone is likely the issue. You will likely have to bring it in for repair or replacement. Go into network settings and make sure that you don't have the network options set to GSM only or something like that. make sure that wcdma or LTE are options selected or bith. also you can choose manual mode to see what networks populate after 1-2 minutes and ry to select the network then. I'd restart the phone and network settings, then if nothing, backup and do a hard factory reset. Taking it in for repair or replacement that'll belijely done anyways as part of the troubleshooting tree.

There are 50 HTC Desire models. I think you have the HTC Desire 510. Since this phone was used in Vietnam, a new APN was likely created so that phone would be able to operate in that country. You'll have to verify that you've switched over to the Koodo SP APN; (Settings > Mobile networks > Access Point Names - make sure that Koodo SP is set as the default APN).

In the same Koodo SP APN window, look for three dots or a cog wheel in the upper right corner of your screen. Tap the icon and select 'reset to default'. This resets network settings to their default values (Koodo) and will remove any APN's that you've added. If you plan on revisiting Vietnam, a new APN can be added for whichever operator you decide to use.

Everyone on this thread is wrong. It's possible for the phone to be locked again. It happened to me, and many other, to have unlocked our phones and have the carrier re-lock it. However, if this happens, it is usually by mistake. You have to call 611 and get them to unlock it again. Although an easy process, it's extremely annoying and is something they should really fix.

Not to argue with you, but I have volunteered on a daily basis in this community for over 4 years and not once did anybody report the phone being relocked again. So though I won't contest it could have happened to you, it's simply not true that it has happened to"many others", as you claimed.

Also, this thread is 4 months old, I'm sure the issue has been resolved by now.
