Questions about unlocked cell phones?
Hello. As you can see, I have several questions about unlocked cell phones. Please enlighten me.
1. What are the benefits?
2. Can only phones that use a SIM card (i.e. GSM phones) be unlocked?
3. How can you tell if a phone is locked or unlocked?
4. If you unlock a phone, can/will the carrier automatically lock it again?
5. Let’s say I buy an unlocked phone off eBay. Then what?
6. From what I’ve read on Google and Wikipedia, having an unlocked phone is good if you travel. Why?
I live in the USA and Verizon Wireless is my mobile phone carrier. I do travel out of the country a fair amount, but I’ve been able to manage fine with phone cards (have to use a land line each time, though).
If I had an unlocked phone and I flew to Mexico, what would I need to do to use it there? Could I make only local calls? Or could I call back to USA? Do I buy a SIM card there or something?
Heres your answer per question you have:
1.The benefits of having an unlocked phones is that you could use it mostly worldwide just insert the particular country’s sim and your off to go..
but take note, make sure the unlocked phones you buy is TRI-BAND, unlocked cellphones will be useless if the phone is not supported by the bandwith of the certain places you go to. there’s 800/900/1900BW so its best to get TRIBAND UNLOCKED PHONES
2.It depends on the maker of the cellphone,sometimes its exclusively for the certain providers use, although you may be able to unlock it, some of the features like web browsing mms, you wont be able to use on other provider.
3.You can immediately pop in any simcard from any network, like your in the US you’ll be able to use Tmobile or Cingular simcard.If you alrady inserted the sim and it still says, “insert simcard, no simcard or read error”, those are the signs phones are locked
4. If you bought the phone from a provider that was originally locked and they ulocked it for you, they might be able to lock it again, but if you originally bought unlocked cellphone they might not be able to lock it especially if the phone is not from them
5.Then make sure that the phone is functioning the way it should, make sure you have warranties on those, make sure that it met your expectations.
6. Like what I stated above, unlocked phones is good if you travel coz you could just pop a simcard from that country and off you go, but again make sure that the cellphone has the right BANDWIDTH so it will be supported by the network, having an unlocked phone that supports one bandwidth is useless, so its best to get triband phones
I think if you have verizon u wont be able to use unlocked cellphones, they have they own networks,check with them first, Also If you’re in Mexico and they have pre-paid simcards that you can buy, you will be able to make local calls, you will have a mexican number and at the same time you will also be able to call locally in mexico and can call back in the US.
