If a phone has dual sim, does that mean that is can never be locked to a ISP?

Hi everyone,

I am just curious if I would buy a phone that comes with dual sims, does that mean that if I go to another country and use the internet providers that they have there, may I be able to do that? What exactly is the difference between only 1 sim and dual sim phones? 

Thanks

dual sim phones are usually unlocked 

ive never encountered a dual sim phone thats locked (the point of dual sim is to allow freedom.. right? (its like being in america and not being able to fly .. wait..)

the difference is that you can have two sims in the phone and use it at once

for example, sim 1 is text/calls only and sim 2 is data only

But when you put a sim from an ISP in a dual sim phone, doesn't it ever get locked? Doesn't the ISP lock the phone right after it puts one of their sims in the phone? Also, you mentioned putting 2 sims in the phone, would you able to do that with 2 different SIM's from 2 different ISP's?

no, they cant lock the phone if its already unlocked (as in carrier unlocked, they can still IMEI blacklist it i guess)

 

you can put 2 different sims with whatever you want

be it different isps, different sims in different countries (you have to have the right frequencies/bands for it to work however) , or even 2 sims from the same carrier.
