Modem,Radio,Baseband. Carrier tuned? Firmware - Samsung Galaxy S9 Questions & Answers

I live in Australia and I know there's carrier firmware for Optus, Telstra, Vodaphone, and just XSA for Australia I would like to know if Optus, Telstra, Vodaphone specifically tune there modem files they provide in there firmware, so using Optus firmware with Optus sim card provides a better reception, battery life network speeds, then say using XSA with a modem that's for all Australia and no specific network intended.
I've also read someone suggesting sometimes carriers don't update there modem files they just stick with one that they found to work throughout a phones lifetime, uncertain how true untrue this statement was.
Thanks.

[Q] do I need to flash my radio to use TP2 abroad?

Hi there,
I'm totally confused as to what I need to do to get my Touch Pro 2 (currently activated on Boost CDMA) to work abroad, specifically Canada.
It is flashed with Energy ROM, Reference version.
Do I need to do a Radio flash? Do I need to tweak some settings? Both? Neither?
I'm going to be in Canada for 3 weeks and plan to use either Rogers or Fido's GSM Pay as You Go (already have the SIM cards), or Telus's CDMA Pay as You Go.
I've read the FAQs and generally understand that this is possible -- just not clear the route.
Thanks,
Simmy
The biggest problem with Canada is our carriers don't want people coming in and using their networks without paying for it, and that usually means your first born here.
The hardware problem is, the TP2 will not work on the frequencies in Canada that Telus has used for the HSPA / 4G network. And using the current CDMA network is not possible either because Telus and Bell will not allow you to put branded phones from other companies on the old network and CDMA systems don't use SIM cards. So if your planning on bringing the TP2 up here I think you may be out of luck.
I took the TP2 to Ireland and was able to use the frequencies there on the O2 network, but to do that I had to unlock the phone and as i have the "world edition" with the SIM card slot once unlocked it worked over there no issue, and returned working over here with no SIM card in it. But again this is a frequency issue and telus tells us it won't work.
Now if when you get here, and you plug a sim card in and it does work, please share, because it means we can manually add frequencies and hook to both the old and new network. And some of us with the original unlimited data contracts (no 10 gig cap) would be really happy to know this.
As for Rogers, i can't tell you. I don't know if they have ever had the TP2 and have no clue what frequency they are using for their phones, though i'm sure it's similar.
Flashing the radio does nothing to add radios or affect your ability to connect to the network while abroad. Its usually just done to improve reception and/or battery life.
You will need your phone SIM unlocked. Then, as the post above suggests, either putting in the SIM works, or it doesn't.
Thanks to both of you for your reply.
So the TP2 won't work on any Canadian CDMA networks, but since it also has GSM, if I stick a Rogers or Fido SIM card in it, it *may* work. In fact, I believe it *should* work. I'll let you guys know how it goes.
And thanks for answering my question re: radio ROMs, Redpoint -- that's what I thought, but was still confused about.
So, with respect to unlocking, is the Olipro page that charges 11 pounds / 14 euros / $20 my best/cheapest option? (unfortunately, i can't link to it here because I'm a new member)
Thank muchly,
Simmy
The device should have no trouble connecting to a normal GSM network in Canada. The Canadian GSM networks use the GSM-1900 and GSM-850 bands. The CDMA Rhodiums use a quad band frequency that spans all of 850/900/1800/1900 MHz channels. You should have no problems in Canada. Enjoy your trip.
You do not need to flash a new radio to have it work in Canada.

[Q] Best Modem for N7105 using Rogers SIM in Canada?

As title states,
I own an N7105, originally bought in Hong Kong to be used in Hong Kong.
I am now in Canada, Toronto to be exact and I am using Rogers as my network provider.
2G,3G and 4G all work fine, but not sure about network coverage. I use a N7105XXDLL5 baseband on my current ROM.
My battery drains like crazy when switching between a low 3G coverage to 2G or low 4G to 3G.
So I was wondering, which modem should I use to have the best coverage in Canada/Rogers? Since all modems in the N7105 (International) means support for carriers outside of the North American carriers, as they have their own variants sold.
Or, should I just stick with my current baseband as it is more 'international', 'widely used' or 'all rounded'?
Much help appreciated,
Nicholas
Anyone know?

Canadian Phone with European SIM

Hi.
I have flashed the stock rom (4.1.1) and removed the carrier lock. Could someone tell me if this phone (Galaxy S3 I-747m) works with european SIM cards? LTE is not a issue here.
Thanks
Igor
It should work but it really depends on the carrier's frequencies.
Have a look at the carrier's website to determine the frequencies supported by their network.

North American model in Europe

I apologize for my ignorance but I figured someone with more experience could assist. I know there are specific models for the NA and Euro version but there are overlapping bands. Think it'll work in perhaps...Croatia if I were to be specific?
I was able to use my unlocked USA model OP1 in the UK, France, Germany, Austria, and Belgium with no issues so the OP3 should be fine for global use too.
What specific frequency bands are you looking for on 3G or 4G/LTE in Croatia?
it wont be a issue to use it, just will lack in some frequencies/bands which ultimately give it poorer reception and speeds
on previous oneplus one and oneplus 2, there was ways of unlocked further lte bands on the usa variant, as they all have the same processor, im sure this will be the case again, if anyone knows how ? please advise
cheers

Can't get 4G+/LTE-A on Three Ireland

I recently switched to the Z5 Premium single sim version and can't seem to get a 4G+/LTE-A connection at all. I can get regular 4G etc. fine. It's definitely not just the symbol either, because the speeds are regular 4G and not 4G+. When I put the sim back in my Galaxy Note 4 it works with 4G+ perfectly. The phone is simfree from Amazon UK on unbranded firmware. I see the modem is a Telefonica UK one though, not sure if this makes a difference. Three Ireland use band 20 for 4G+, so I know it's compatible. Would flashing firmware from a different country help? Is there a way to flash the modem or baseband of a different firmware to make it switch to 4G+, maybe Three Sweden or something? Is it a problem with the network? Thanks, Griff

I would check your APN first to make sure it matches your carrier, if that does not make a difference I would find a firmware that matches your carrier. On AU customized I get the 4G icon, on Singtel I get LTE and VoLTE but the speeds are pretty much the same. I am in the US though and what they call LTE here is not really LTE. So on some firmwares I get the 4G icon and some the LTE icon but like I said the speeds are the same.
