[Q] 3g does not work

Similar Issue
I have a similar problem so I thought to post here.
I have a I5500L.
It came with this firmware out of the box I5500LUYJP9 (2.2) it was locked to Movistar (Venezuela).
I unlocked it with SRS to use it with my carrier (Digitel Venezuela).
No matter what I try, I cannot make it work with 3G, only EDGE.
I've tried many things, changing bands, forcing WCDMA, and a lot of tricks found on this and other forums, but nothing works.
It's not that it doesn't work with 3G and goes to EDGE, but that te phone is only working on basic GSM, and cannot connect to the network if I change any setting.
Funny thing is my wife has an I5500 (without the L), it was bought unlocked, it came with some European Firmware, and hers works perfectly with 3G.
She has the same carrier as me.
Another thing to note is, my phone detects a network called "Digitel", her phone detects a network called "DIGITEL-GSM".
¿What could be the problem?
¿Could I flash some European firmware to my phone to make this work?
¿Will this affect the SIM unlock?
Thanks.

Thanks.
What are the implications or possible sideffects of changing the baseband?
I mean if a baseband won't work, there should be another one that does right?
I'll be doing some reading, but a head's up wouldn't hurt.

there no danger in changing basebands, the only thing is, some will, and some wont work. you should just try the baseband from wherever you are 1st, but if that doesnt work, try another. doesnt matter if you are from UK and you use an american baseband, if it works, its completely fine
has it worked?

You can't. That phone uses different bands then the US. You will have to get a world phone.

"World phone", also known as a quad band phone. If you want an unlocked phone to work on T-Mobile's LTE, it'll need to support band 4.

Well, I don't think there's nothing much you can do with your phones as the US mobile network operated at different band and your device may not be supporting that band better option for you would be getting a new phone form the vendor other than this no other option can help you much with the problem you are currently experiencing.
Hi. :laugh: today my problem is solved, i can use 3g network all time, thanks all everyboby , so happy :laugh::laugh::laugh:

Sorry to tell you I havent. Same say you can brick the Phone by installing another firmware others says that nothing will happen because the hardware is different meaning this Phone cant recieve the bands that is not suppose to. I dont know. I've read other sites seraching for a solution to this problem with no luck. I guess we have to wait till a custom rom that works.
The model you buy works best in the region it's bought in. Some networks will cross-over when in a different continent, but not all, usually. You can't add frequencies to the phone whenever you want, as far as I know.
I have installed a e2303 software on a e2306 phone and it works fine, but still has the e2306 bands.
Maybe in the future there is a way...
