Assuming you are using a GSM carrier like At&t or T-mobile, you can swap the SIM to a different, compatible handset at any time without any penalty.

I'm going with no.

For example those ATT smart phones that won't let you install apps even when unlocked and those sims from Tracfone, etc. It's a deep well or tar pit depending on your point of view.

An ATT or T-Mobile SIM can be used in a *compatible*, unlocked handset. The OP wasn't referring to apps or data per se, nor were they referring to using Tracfone SIMs.

Would it matter?

That is, while I know you know what's up with Tracfone SIMs and that handset from ATT that when unlocked results in a confused owner, my thought is that it's a tar pit of issues.

I guess I wasn't specific enough but I am a T mobile subscriber and am wanting to go to an unlocked phone. Was wondering if all I needed was to have a gsm phone and put my Sims card in to have it work. Thanks for the answers.

Why I went with no.

There are a few considerations and the basics are that you want to match up the T-Mobile GSM services and frequencies with your new phone. Many will work but it's not as simple as what you asked. Why not supply a phone and where in the world you are and folk can check it out?

This was my first time on the forum. I will be more specific in the future. Must learn from mistakes. Thanks for the feedback.

Phone has to have the following frequency bands
by Pepe7 / June 15, 2013 9:15 AM PDT
In reply to: More specific

Bare bones, the unlocked handset would have to have 850/1900 GSM frequency bands for voice. 3G/4G Data on T-Mo requires 1700/2100 UMTS, and in some area now that have been refarmed, 1900 UMTS as well.

Looking at the LG nexus 4 or the HTC one

Nexus 4 is fine; HTC One, depends which version

In reply to: Phones

Here are the specs-

If you are buying an unlocked *developer's* version of the HTC One, be aware that it lacks the ability to utilize T-Mobile's refarmed AWS services for HSPA+ (1900 MHz band). It does however cover T-Mobile's LTE bands though. If you happen to be in an area where LTE hasn't been rolled out yet, and require 1900 for HSPA+. you would be SOL. Comments regarding the developer's version contained in the following review of the T-Mobile version of this handset-

What I don't know is, if the 'developer's version' is the same as the 'international version' mentioned here:

You should ask @ to clear this up before you plunk down $$$ for the HTC One. I wouldn't want to deal with a phone that did not provide you with at the very maximum speeds your carrier of choice was offering where you reside/need to use the phone.

In reply to: your thoughts

Why do you need/want an unlocked phone? Just curious. Do you plan on relocating to another area (different state or country) in the next two years? If not, ideally you should consider taking advantage of the subsidized pricing on these phones from T-Mobile, etc. A new, unlocked HTC One will be in the neighborhood of $650. The Sony you mention is ~$500.

Another thought. You could buy a subsidized T-Mobile phone, have it unlocked at a shop for $30-40 if you eventually think you will need to switch to another carrier. YMMV. Also, you could pay the ETF and get out of your contract by selling the phone outright too.

Not sure when a smaller city like St Louis will be getting LTE, so that may not even factor in for you in the near term anyway. A device which is capable of HSPA+/42 may suffice.

That's for the input
by Robbins204 / June 17, 2013 2:42 AM PDT

Under contract at this time not due for upgrade yet the phone I have is broken. Using a loner. Have no plans of relocating just want to get out from under the carrier. May go to different carrier. Just would like the freedom. It's going to cost 150 just to replace what I have with a refurbished model anyway. Thought I'd add a little more and get what I wanted...

I would consider the refurb
by Pepe7 / June 17, 2013 4:51 AM PDT
In reply to: That's for the input

FWIW, of the last 15 or 16 refurbished devices I have owned, none were defective. Many in fact sold as refurbished are simply returns from businesses, etc. that were previously sold/opened as new but never used. $150 vs $500 seems like a jump just to get a new phone. Food for thought anyway.
