Heading to Ireland... sim unlock question

ok, hopefully I wont get flamed but havent found the 5 y/o answers than I need.... I have a Tilt with AT&T, Im using an WM6.0 Alex ROM (may switch to Duttys)... Ill be heading to Ireland this weekend for a week and I wanted to make sure I understood exactly how I can use my phone when Im over there...
I know how I can get the code for Sim Unlocking the phone but I was curious about where I should get the new sim card and how rates will apply for me when Im over there...
Assuming I get the unlock code from AT&T:
1. Where should I purchase the sim card to use in Ireland?
2. Do I need to call AT&T to get an international plan for any reason?
3. What carrier would I be using while Im in Ireland?
4. What rates would apply for me calling the US or in country?
Any help would be appreciated... applying flame retardant gel now... go...

1. Go to Ireland local phone retailers to buy a SIM card.
2. No. If you don't want to receive call from your America phone #.
3. Your choice.
4. Once you pick the carrier, go to their website to see the rates.

It kinda makes me sad how people are afraid to make new threads now..
makes me wonder which direction web-forums are going.
Sorry, little OT

Your US Tilt should work fine with no change in SIM card, though the local calling rates will probably be a lot higher. I just got back from a swing through about 5 or 6 European countries (including the UK, but not Ireland) with my US Tilt and I was able to make and receive calls in all of them.
AT&T does offer a $5/mo International plan that cuts 20% or so off the per minute rates, but I didn't bother signing up for it as I expected to make only a few calls.

So do I even need to sim unlock it then?

if you are planning to use your own sim card in ireland and pay the roaming rates then you will not need to sim unlock your phone and you will be contactable on your current phone number.
if however you decide to purchase a sim card in ireland, you will have to sim unlock your phone. I know that this is meant to be relatively straightforward but I never had to do it.
If you decide to get an irish sim card you have the following options:
Meteor: http://www.meteor.ie/personal/pay_as_you_go/price_plans/
o2: http://www.o2online.ie/wps/wcm/connect/O2/Home/Personal/Price+plans/Speakeasy+prepay/O2+Experience
Vodafone: http://www.vodafone.ie/planscosts/prepay/current/
There are 2 other operators in ireland, tesco and 3 but they are very unpopular. I'm currently with o2 which offers the best value for me. If you want a relatively unbiased view go to the carphone warehouse as they sell all brands of sim-card and will recommend the most suitable
Whatever you do don't connect to the internet whilst in ireland except using wi-fi as data costs are ridiculous.
If you have any other questions feel free to ask.

If I get a sim in Ireland, will that give me a new number that works on that network?

It will be like totally dumping AT$T, number and all, and switching to a brand new carrier

Not unless you cancel it. It would look to them as if your phone was off while you were using another SIM card.

So it sounds like I should only use an Ireland sim card if I plan to do a lot of local calling... If I only plan on calling US numbers then I should just keep my AT&T sim card and pay the international rates... is this correct?

Im going to take no response as a yes...

You'll be charged 1.29 per minuite or .99 cents depending on your plan with AT&T no matter where you call.

Dual Sim (HSDPA Data Compatible) ?

Hello,
I am looking for a dual sim adapter that I can use with my 3UK sim for HSDPA/3G data access and my Vodafone sim for texts and voice calls.
I do not mind cutting up my SIMs or having to restart my phone to switch between sims. I have heard that the "Simore Gold 1" sim works, but 70€ is too far out of my price range!
If anyone has any recommendations or experiences with dual sim adapters on the Diamond, that would be great
Many Thanks,
T

Do you have this card working? How do you change SIMs within the Phone application on Win Mobile 6.1?

That is a SIM cloner, which works only (I believe) with v1 sim cards (I have one myself). These went out of usage many years ago. There is no way to clone modern cards yet reported in the wild. Worse using SIM cloning software on a modern sim card may break your sim.
I don't have the information to hand, but it is out there. These SIM cloning kits are not a solution for modern, data enabled, SIM cards.
I've been closely following dual sim options since the release of tytn. I've bought many, and not had any work to my satisfaction. The only option that I have heard positively reported, for phone and data, is the simore gold.

I wouldn't! )
Just offering my humble opinion. I looked into the possibility of sim cloning some months ago as I have two sim cards and it would have been nice to be able to use both of them without going through the hassle of rebooting every time you want to switch.
I searched and searched for hours and found plenty of information (on XDA and other websites) and although I don't remember all of the technical details, it isn't possible at the moment unless you want to risk breaking your sim card (which sounds very likely from what I read).
I'm not sure what sim cards are used in India. I do know that the v1 sim cards can be cloned but (as mentioned in the previous post) they are pretty much out of use and have been for some time, so I would think that it is unlikely that you have a v1 sim card.
You can check out the articles here: http://en.wikipedia.org/wiki/SIM_cloning and here: http://en.wikipedia.org/wiki/Sim_card.
The first article says at the top of the page that it needs some clarification but it does discuss the sim cloning scene in The Bourne Supremacy (referring to an earlier post in this thread) and how long it would have actually taken if it were possible; 4-8 hours to extract the Ki and some knowledge needed of the SIM card's PIN (CHV1). (Citation needed for italicized text.)
It also mentions a 40% chance of damaging the card. Sorry, but those odds are a little too high for me!
The second article is a bit long and technical but might be helpful to you. (I started to get a headache about halfway through it! ROFL)

I'm seriously considering the Simore Black 1 (v6). Can anyone confirm that 3G/HSDPA data and "3UK" sims work with this adapter?
Thanks

Wow, that's really expensive! Have you looked at this? http://cgi.ebay.co.uk/Dual-Twin-Sim-card-Holder-Adapter-Interface-Ghost-UK_W0QQitemZ280289223146QQcmdZViewItemQQptZUK_MobilePhones_MobilePhoneAccessories_MobilePhoneBatteries?hash=item280289223146&_trksid=p3286.c0.m14&_trkparms=72%3A1300|66%3A2|65%3A12|39%3A1|240%3A1318
I know I'm a newbie and might have gotten it wrong but the description says that it will take two sim cards and is 3G supported. You also don't have to switch your phone off in order to change sims.
DOH! Just checked your post again. This one is NOT supported on the 3 network. I'll go ahead and post this anyway just in case someone is looking for a dual sim card and doesn't need 3 network support.

I appreciate the help

When looking at these type of devices you need to consider very carefully what you consider "compatible".
Advertisers may consider the ability to make 2G phone calls as compatible. These devices may not allow 3G calls, or data.
I'm toying with a simore gold, because it will be worth it if it works with 3G and data. I'd like some more anecdotal evidence that it does before I commit, at that price, though.
I'm done with buying cheap dual sim adaptors. I've got a desk draw full of them that are unsuitable for my needs.

Ah, I see. Point taken. It's probably best to avoid a newbie's advice! LOL I haven't actually used one in a while but will definitely consider carefully before I buy another one.

Hi all! Just a contribution from me: I bought from ebay a Magic Sim 20th dual sim. In other phones works but in Htc Diamond only sim1 is recognised.....Does the analog ones really works? And if so, where do i buy it? Thanks!

I'll be waiting too for those who had an experience of using a working dual sim adapter on their diamond. I hope those who tried simore gold will share their comments.

euro galaxy working in japan?

hi,
will my euro galaxy s work in japan (where I am going on vacation)?
Thanks,
Sent from my GT-I9000 using XDA App

It will work (roaming) but it probably will not work with a japanese sim card

Like zombrex said.
It will work, but I had problems calling and receiving calls from japanese cell phones. Apart from that everything worked for me.
Sent from my GT-I9000 using XDA App

3rd confirmation. I could use roaming in Japan. The European model is identical to the international model.

Just got back from holidaying in Japan. I can confirm that the Galaxy was fine there although I didnt make any calls (expensive!), mostly used data services to retrieve and send emails using UK sim card. Used wi-fi points and skype/tango where possible.

Thank you guys for the info, I'm glad my beloved galaxy will work in
Japan.
Are prepaid data or/and voice sim cards available in .jp to avoid
horrendous roaming charges?
What is the wifi hotspot situation in hotels and cities in general? Are
they mostly free?

I think there are no prepaid cards in japan like you know them.
Can't remember using free wifi hotspots except in the hotel. But once there was a free hotspot in a club. That was the only one i found^^

Hi !
I have the same kind of question.
I will go in Japan for 1 year, and as I saw that they sell Galaxy S in Japan, I was wondering if I could use my Galaxy S with a Japanese Sim card.
Do I need a Japanese rom ? Or any configuration ?
Thanks

Up !
No one can help me ?

If your phone is unlocked you'll be able to use a japanese sim

it wordks,japan user the different sim card size(smaller),you can buy the sim card cover to fix it.

Thank you DrFredPhD and eim886 !
The Rom doesn't matter ?

I looked for a sim card cover, but I only found a sim card adapter for micro-sim.
Where could I find a sim card adapter to use a japanese sim card on my phone ?
EDIT :
I found there is only 3 sizes for sim card : standard, mini-sim, and micro-sim.
But which one is used in Japan ?

hey trynium, did you find an answer to your question?
I have a North American version (Canada Bell) i9000 and really don't want to buy a new phone when I have a perfectly good one right here. Would the sim adapter work? Which network did you use and how did you go about it?
I was wondering if the North American version phone can run on Japan's network... if anybody out there could help, it'd be much appreciated

I went in Japan later than I expected.
I took a prepaid phone, so I could not really test with my SGS (no internet connection, lot of restrictions... for prepaid phone).
But the good point was that the sim card was a standard one. So sim adapter seems useless in this case.
The harder in Japan, is to buy a sim card without a phone. From what I know, there is not much problem than that !
By the way, sorry for the (very) late answer...

My apologies, this was my misunderstanding around CDMA tailored devices.
I had conflated CDMA with a version of using eSIM or something of that nature.

To answer your question, data will work on verizon in some areas, but voice won't. Same with all Huawei flagships of late.
Your only hope would be rooting and perhaps enabling VoLTE on verizon, in which case there's a small chance you could get it working.

Verizon uses the SIM card only for 4g data, LTE, but for voice it still uses CDMA. I really don't understand why Verizon and Sprint continue using this system, they seem to be the only one in the world with China and maybe some other areas, but most of the countries rely fully on GSM for both data and voice. This is the reason why the p20 pro will only work for data on Verizon but not for voice unless, and just maybe, you use a Chinese version I think the L00 model that uses CDMA too.

Very interesting because the U11 doesn't have cdma either but voice works on it over LTE. If we could get that on the P20 we would be in business

You are right. It seems like now Verizon is trying to use only services through LTE like VOLTE and is trying to turn off its old cdma network.
https://www.androidheadlines.com/2017/06/htc-u11-can-used-verizon-even-without-cdma-support.html
Even though it seems like for this the cellphones need to go through Verizon approval and they are not 100% functional like it would be with ATT and Tmobile, which network is 100% GSM/LTE. You can see on the link below that the phone was only approved to use one band on Verizon which could cause really poor service.
https://community.verizonwireless.com/thread/942418
Knowing this and all the issue between Huawei and EEUU government I seriously doubt this approval would happen, but who knows.

On the U11 it had 2 of the 3 verizon LTE bands I think it was missing 13 maybe? If i could get 2 out of the 3 bands to work on the P20 Pro I would probably try it

I think you missed the point in the last link I posted. There it is mentioned that the cell phone has most of Verizon bands if not all but only 13 was authorized to be used and this was what causes many of the issues with the U11 on Verizon network.

Your Pixel says NONVZW because it was not bought directly on Verizon but it is a cell phone that is configured to work on both GSM and CDMA including full compatibility with Verizon so it shouldn't be considered as the same than P20 pro but if you still want to do it go ahead and good luck.

Anytime the same discussion. Thia phone is not official supported by Verizon. It will work on GSM Based Networks. But not on CDMA.

who ever said the US did not have sims is right.
at one point in time the cdma guys did not have a sim card and in some phones still to this day out there they may or may not have a sim. if the person buying the phone gets bull **** from the sales person and buys a locked phone good changes are they may or may not have a sim.
now update to this day.
most if not all companys here have a sim now. they were forced by company's over seas and other gsm company's here being cheaper and no locking you down to a pay over 2 year plan that you more or less are selling a kid to the company to pay the bill.
but I love the fact that we get sims now. If they tryed to pull that bull **** with me now lol.

It's got nothing to do with that. CDMA does not require a sim, never has. LTE is what the sim is for because LTE is actually a GSM technology.
I dont know alot about the U11 but from what I could see from a quick search it actually does have all the Verizon LTE bands including 13. 13 is the most important one because its verizon main LTE band.
Guess which band the P20 pro doesn't have...13. It probably will not work and even if you could somehow manage to get it to. it probably wouldn't be a very good expensive, but if you want to spend 700 bucks to try to prove us all wrong more power to you.

unless you didnt get a mobile phone until like 6-7 years ago...you would know that prior to that Verizon was primarily only CDMA and DID NOT USE SIM CARDS.
you are simply showing your age or lack of experience with mobile phones when you assume Verizon has always had sim cards...which is simply not true.

I take it that you travel often? Esim might be the better way to go or have a decent roaming plan. Personally, I prefer to have local simcards as its often cheaper.

If the telecom provider supports esim and your phone has esim, that would be one way to avoid switching simcards or have a phone that has dual-sim that way you can keep the sim that you use often inside your phone. It won't prevent you from having multiple cards but it will allow you to switch less.

I akrewady have my unlimited data uk esim but it's only for the eu not for Swizerland or andorra or turkey.
