What happens if I put a data-only SIM (like from a tablet) into an unactivated S III (as in no CDMA connection). Can I just use a tablet 4G data plan with no 2G/3G calls or texts?
I already know how to get free VoIP and free texts through internet (ToIP?).

Is my XDA IIs 3G?
no
it's
not
So if i put a 3G o2 sim card that i have in it what will happen?
You phone will work, that SIM card just enables you to use a 3G phone as well as other non 3G frequencies.
but some operators like the company 3 seem to block their sims from working in non 3g phones
I have had no luck getting my Vibrant to work with my T-mobile blackberry plan. Phone works, but no data.
If I get a Captivate, unlock it, will it work with T-mobile's blackberry plan for data?
I don't care if it's just 2g and not 3g, I just want data...
I was told by AT&T that it wouldn't work because the data is provisioned differently. I wanted to keep my Bold 9000 for work and the Captivate for all other times and couldn't do it. I'll have to assume that T-Mobile also provisions their data differently.
At&t 3G runs off a completely different radio frequency so an at&t phone wont work on T-Mobile 3g. It will work with 2g and data provisions have nothing to do with it. Still a GSM network. Just get your unlock code for your sim and switch away

An unlocked Captivate will work on Tmobile but you will only get Edge for data.
There is a big draw back as these phone were never design with anythin less than 3G in mind. When ever I was using data (edge) all my voice call went straith to voice mail with no indications of any missed calls.
With Wifi it's fine. Even peoples with AT&T 3G have these problems when they travel to an area with only 2G coverage. Even a person in India told me the same thing with his Galaxy S.
Yeah with edge you cannot talk and use data at the same time. That's why when you're using data it will not allow calls to go through until the data stops transferring.

Hello, for the last couple of days I've been on the hunt for a dualsim smartphone that can receive 3G signal on both of its sims, simultaneously.
At the moment I own a device that can do 3G/2G for sim1, only 2G for sim 2 and I have to use 2x3G sim cards(the provider emits exclusively 3G signal for mobile communications); in this scenario, one sim card is unusable.
Now my question emerges: is there such thing that can certainly(I can't afford to just buy devices that could possibly do this based on ambiguous internet discussions and test them out) keep 2 sims, both 3G, operational simnultaneously(not with the tricky switch, I will be needing to get calls on one of the sims, even if the other goes to standby)?
Thanks!
Me and my family will be traveling to Jamaica this weekend. From looking at Sprint's coverage map, didn't see any coverage for Jamaica. Question, w/out enabling International services for our phones, is there an app we can use for texting each other? Would this only work if we are connected to a wifi network?
Update: Talked to Sprint, we have Sprint Global Roaming (not warming) which is free. We'll have unlimited text/data, but we'll get charged for any voice calls, $0.20/minute. We will have to connect to a GSM network when we get there.

Do they have to activate something on your phone to connect to a GSM network? My father in law is thinking about switching to our family plan but goes overseas to the Philippines a couple times a year and is worried about connectivity while over there which is all GSM. Thanks!
They updated our Profiles, not sure what got changed.......................then when we arrive in Jamaica, we'll have to go into Settings, More Networks, Roaming, Roaming Network, Automatic, Roaming Settings, check International Voice and International Data..........then Settings, Connections, More Networks, Mobile Networks, Network Mode, Select GSM/UMTS, then select one of the three networks that will be available.
Here is my query, during travel abroad from US: On my Oneplus 7Pro, I have data enabled SIM1 (UK) and US TMobile SIM2 (no-data on international roaming). T-Mobile calls/SMS to the US using wifi calling is free from overseas.
Can my dual-SIM phone use "WiFi calling" feature of T-Mobile, by using the data connection from the UK SIM?
I can use 2 phones and setup wifi hotspot, so that TMobile uses the wifi of the local SIM, and wifi calling is enabled. But I want to use one dual-SIM phone. Is it possible?
Thanks!
