[Q] Can you hack a Captivate to use European SIM cards? - Captivate Q&A, Help & Troubleshooting

Is it possible to hack an American Captivate to use European SIM cards? Specifically a prepaid card from Poland.
My wife is planning a trip there and was curious if she could avoid toting around both a cheapo prepaid phone, for the phone function, and her Captivate, for everything else. Her phone already has CM7 on it, but could be changed if needed.

Unlock it. It's a one time thing. Then you can use any sim card in it. SGS Unlocker from the market should work. I've never used CM, but unlocked mine while on Cognition 4.5.3

I am using one in India, I hope u can also use one there.

just search some pages and u can unlock ur cappy urself..i got it from canada 6 months back to india..and unlocked it myself..
its not a hard process...and then check another service provider's sim card to check if the process was successful or not...

Root
Download galaxy s unlock from the market
Run it
Enter this code in your dialer:
*#7465625#
If it says all the locks are off then you're unlocked

I'm heading to the UK at the end of the month. I'll be in both England & Wales. I've used Galaxy_S Unlock from the market successfully... Now my question is: which SIM to buy? I've (obv) never done this before, & there are apparently a plethora of choices. Is the Captivate limited to a specific UK carrier?
*Edit - also, will I need to use a specific carrier's SIM to get 3G? Or will I be able to get 3G at all?

That all depends on what bandwidths the carrier use. You should be able to at least connect to a network with any Sim. But I believe 3g requires 850 and 1900 mhz bands. Which is why you can't get 3g on Tmobile even in the states.

OK, so I need to find out if there's a UK carrier that uses those bands. I need both, correct?

Either one would work, but both is recommended.
If it only has one and the signal gets weak and it tries to hand off to the other you'll lose 3g until you get into a better area.

the phone is SIM unlocked; you can use on any GSM carrier.

I'm almost positive that you should be able to pop in any sim card, pre- or post-paid, and it should work...
i just tested it with a nextel chip with a plan but no data service and i still get no bars??? i will try to put up some pics....please help if ya can...thanks
As far as I know Nextel doesn't use GSM networks it has it's own iDEN network, I don't know what the difference is, or if it should work with a GSM receiver but I can't say I'm surprised it doesn't work. Also from what I've heard, the phone has only received FCC certifications on T-Mob and AT&T for the phone you have, Verizon passed separately. Again, don't know if this helps, but I'm not shocked it doesn't work. Your phone is carrier unlocked, it came that way from HTC and unlocking the bootloader has nothing to do with which carriers it will work with.
no all i did was i bought it on a tmobile network through google then i had unlock the bootloader then rooted the phone now is there a way to use differ carriers??? i did not buy it unlocked......from google.....so is there a way ?

Dude... your question is moot! The phone, even if bought on a T-mobile line, IS NOT LOCKED TO ANY SPECIFIC CARRIER! You can pop in ANY GSM SIM CARD, and it will work. I bought mine on a T-mobile upgrade... but I can throw in an AT&T, Rogers, Fido, Vodaphone, etc., SIM, and it will work just fine.
o okay will try it out with att thanks...

[q] lg revolution 4g unlocked

Has anyone ever seen the one click unlock or the unlock codes to get this phone to use another companys sim card... Ive checked all over and cannot fund anthing please let me know
Which company that uses the same frequencies that Verizon does were you hoping to use your phone on?
I've never heard of a Verizon phone that you could unlock... Well, except maybe their quad-band "world phones". I've had Verizon for years and this is the first with a sim card. I'm not sure, but I think the sim is just for access to their lte "4g" network, wich is of course probably just different enough from atts lte to not be interchangeable there either.
The sim card gives access to the network in general. Without the Revo is useless. I tried to take out my sim to save battery and not use my 4G radio before I relieve I could turn it off. Also, for OP I don't think there is a way because of how the phone works. Then again, I'm not a dev so I could be completely wrong.
the sim card in the revo is just for the lte access and is phone dependent it will fry its self if put in a different phone. also just a quick side note i guess verizon is moving to sim cards too (from what i heard from an associate on the phone the other day).

Yes. The SIM card cannot be unlocked and this phone will never be able to be used on a different carrier.

[Q]Travelling with Nexus One

Hello,
I have a quick question about a Nexus One I got with Vidéotron (a Canadian Carrier - I believe it is compatible with the T-Mobile network).
I am going on a trip to Los Angeles and was thinking of picking up a local prepaid sim card and just swapping it with my Videotron card (will be using a yak calling card for long distance).
Will this work? Do I need a special code to get the phone to accept the card?
Aside from using google talk or similar computer based alternatives, does anyone have a better suggestion (cost-effective!) for using my Nexus One in LA without getting dinged with roaming?
Thank you in advance!
Yes you can get T-Mo 3g http://en.wikipedia.org/wiki/UMTS_frequency_bands .
Was the phone sold as unlocked? I know the ones sold in the US were but I am unsure about the carrier branded phones. The best thing to do is get a local SIM from another carrier and test it out before you go. I'm sure they are able to give you an unlock code if you just call them.

[Q] Lumia 521 on AT&T

Is it possible? I have a lumia 521 for metro that I'm currently using to work on apps but my family plan is on AT&T. I'm coming from android so is there a ROM I have to flash to use a sim card for them?

SIM unlock and ROM flashing rarely have anything to do with one another. SIM unlock (depending on the locking carrier) may be free, have a nominal cost, be only available on the grey market online, or be utterly unavailable at this time.
Be aware that AT&T uses different cellular bands than T-Mobile / MetroPCS. Make sure that the phone will work on AT&T first! You may find that you're unable to get any speed better than EDGE...

The bands are all the same so I'll try finding a SIM unlock, thanks.
Guys, I am looking for unlocking my Nokia Lumia 521 which is tied with the T-Mobile. I got it couple of days back when I came to US couple of days back, but I am based out in India and not been able to use it with the Indian Carriers.
Please read the FAQ... There aren't any ROMs that ignore the SIM locking mechanism. You'll need to either call T-Mobile (or MetroPCS for the OP) or purchase an unlock code from various online sites.

[Q] Use SM-G900A (AT&T) in Europe?

I believe the answer to this is "no", but:
I have access to an AT&T SM-G900A that is not being used. My daughter is about to move to Germany for an extended period.
First, can the phone be used in Europe at all?
I certainly wouldn't want to pay AT&T's probably-exorbitant rates, so then: can we buy a SIM card there to use in it as is? (pretty sure the answer is "no")
If I unlocked the phone (by buying an unlock code), could it then be used with a Europe-purchased SIM card?
I suspect this is all more trouble than it's worth and I'm better of just finding a used unlocked GSM phone of some sort.
Much thanks.
if you can use it abroad unless you unlock it first.
I have a galaxy s5 att and I am using it with another carrier here in south america.
only bad thing is that the wifi hotspot will not work for being a simcard from another operator, only work by usb tether.
It's working well. I bought an AT&T Galaxy S5 from USA and now I use it in Romania.
The WiFi hotspot is not working, but all the other features work very well.
Probably, after the bootloader will be cracked and we will have the opportunity to install a custom rom or an unbranded rom, the hotspot will function as well.
Enjoy your gadget !
All answers are correct. I was formerly in the U.S.Army and took an old T-Mobile HTC Dream over to Kuwait with me. I called T-MO and got a sim unlock code for free. Upon getting overseas I established service with a GSM carrier over there and popped in my sim card and whallaa! My phone completely worked in Europe and the middle east.
