Costa Rica data issues?

I am in Costa Rica for a week and am having in interesting problem with my phone. I purchased a local sim card and it works great, except the data seems to have odd issues. For instance, I can use Google maps just fine most anyplace I have a signal. But if I try to use the xda app, or the web browser, it doesn't work. I would think that data connections are all the same and it should work? I am using wifi at the moment and it works fine so I know it's not the programs. Any quick ideas? I am here for 4 more days.

My first guess would be to call the provider or ask a local user for the correct APN settings.

I looked up the APN settings online and they are correct. It just seems odd to me that data from Google maps would work just fine over the cell side but nothing else works. I would think it's all or nothing.

Yeah. Usually if your APN is bad, all data is hosed. The provider may be selectively blocking traffic... Eg: if you're on a prepaid dumbphone+data plan, they may grant a narrow range of whitelisted urls or data providers. Not sure.

What data signal does the local service provider use? The captivate's modem can only pick up signals on the 850 and 1900 bandwidths. That's why, for example 3g won't work on a captivate with a tmobile sim card.

I have a widget that says I have an HSDPA connection at 7.2. I am leaning towards some kind of filter or white list on the cellular providers end. Its not to big of a problem since the place I am staying has wifi. But I would like to know the reason for sure in case I run into it again someplace. The other oddity is if I go into marketplace the items I have purchased don't show up in my apps selection. And in Google maps, I can see where I am, but the ability to share the location is greyed out unless I have wifi. Even though the satalitte image updates to wherever I might be. So the data going through is very selective.

I can also send texts to other local phones here but not mms pictures. Very unusual to be able to send/get some data but not all. I did read on another site that prepaid sim cards in Costa Ricardo don't have data but that wouldn't explain my ability to use Google maps to see where I am.

Do you have modem locked in to to one freq only?

I don't believe so. I don't think I flashed anything new since I flashed the darky rom a while ago. At home it switches from E to H which I believe is a different frequency? And I also at home have a dual sim setup swapping between att and tmo as needed. So I would think it's not locked on a frequency. I am flying home tomorrow, but I do appreciate the ideas. And maybe this thread will help someone else.

A search on Google on the subject of blocked IP addresses shows that Costa Rica ( particularly ICE ) has a known problem with being blocked by many providers. That may also be part of the problem.

[Q] help Mobile Network Connection but data not active

I put in CM 9 in my old tab 7 and loved the performance so much i wanted to start using it again.
Was using it wifi only.
Got a month of prepaid data from AT&T.
No problem with connection to network but there is no data connection.
Has anybody seen something like this when trying to re-establish service with carrier? or just with the symptom of solid connection to network with no data connection.
I thought it would be modem file so I will try some others, but I should have the right one in the build.
I will be getting a new SIM in case it an AT&T issue (ugh), but I need time to drop by store (ugh).
Did a complete reset. Clean install and the APN are right.
Mobile Network apps (Kabits) shows cell connected nornally, just no data.
Any thoughts??
thanks much

Post your apn here?

Phone repaired, now can't connect to 3g

Hey guys,
So i broke my Xperia Z (C6603) screen 2 weeks ago and just got it back from my insurance company a few days ago.
They somehow unlocked my unlockable bootloader and also sim unlocked the phone. I was not disappointed with this
But, i can't connect to any 3G networks since getting my phone. And since my provider only supplies 3G and not 2G, i'm screwed.
I've factory reset, flashed various stock roms, 244, 423 and also flashed CM10.1 and CM10.2. No luck! I figured one would have a baseband that worked properly?
Everything else works fine, wifi, calls, nfc etc. But when i go into *#*#4636#*#* and try to set the preferred network type, i can't select LTE etc, it just defaults back to WCDMA. Also i have no option for LTE in the mobile settings network type (i did previously). Only WCDMA only, GSM only or WCDMA (preferred)/GSM. The last one should work, but still can't connect to 3G networks. Every time i try, it tells me "could not connect to the selected network, check your sim, blah blah". But it connects to the 2G variant of that network just fine.
My APN settings are fine, as i copied them from my HTC One on the same network. And the imei isn't blocked according to my provider.
I have tried another sim and this sim in another phone, so there is nothing wrong with my sim cards. And i doubt there's anything wrong with the sim card slot, since 2G wouldn't even work then. I'm on Three UK and have phoned them for help, but they were useless and fobbed me off to my insurance company.
Any ideas? I'm pretty much out of them

The fact that they unlocked a locked bootloader and SIM unlocked the phone sounds a bit dodgy to me.
You could try downloading the APN settings, go to Settings>Xperia>Internet settings.

Yeah i was thinking that myself, and have read reports of them sending people replacement phones with blocked imei's etc (stolen phones).
Think i'll be sending it back to them. The internet settings didn't work, but thanks for the suggestion

Yeah probably a good idea, get them to explain why they had to unlock the bl and SIM lock in order to replace the screen!

You on 3 by any chance?

Yeah i am.

How do you find your signal? Obviously having no 2G network is, in some cases, a disadvantage.
I only ask as on my HTC One S my signal was fine all the time, now with my Z I find my signal patchy and it takes a while to find any.
Oh and I wonder, does your My3 app work? Mines not working anymore, it always thinks I'm on wifi so won't open any payment pages.

My signal on the Z was always great when it worked. On my HTC One it's not so good. The three app won't work on my Z, since i obviously have no data connection at the minute. But i never had any issues with it.

Slow data speeds in apps

EDIT: So the internet will work GREAT in Speedtest.net, and Chrome, but myATT, Facebook & even Google Play all time out/refuse to connect to anything while on mobile data. Edge works great albeit slow, LTE does not.
So i got my HTC One yesterday, immediately S-Offed and flashed the Google Play Edition RUU following all of the guides here. Currently on the 4.3 OTA from google.
My problem is, my data speeds/connectivity, more specifically in apps (Facebook, myATT vs using a browser) are slow to nonexistant and it'll just time out. WiFi works great.
Tried the included google Radio, the official AT&T 4.2 radio for the One, and the 4.1.2 OTA update radio as well. All exhibit the same symptoms. Compared APN settings to my gf's phone (HTC One, stock) and they're identical. Any ideas fellas?

Also tried resetting APN's to default.

Also disabled LTE, so it was just on HSPA+, and it worked great. Flashed a few other radios and nada. Tapatalk works great too, just facebook and play refuse to connect over mobile data on LTE. GF has a one that is stock and it works fine right next to me.
I'm stumped!

So your GF has a stock HTC One and data on her LTE works fine. Yet on your HTC One is does not, but HSPA works.
By that of course I would stay if your HTC one on stock showed the same issues? If it did I would its either network related or hardware.
Call AT&T and double check if the HTC one is allowed to connect to LTE. It could be a provisioning problem on their end.

Would provisioning affect apps? I'm about to do a factory reset/wipe data, because I've got it narrowed down to just the Facebook app & Play store not working on LTE. Literally. Everything else is peachy.

No, but some Google Apps might use Google's DNS whitch might cause issues. As for the Facebook App I can't see why it's not working.

Everything worked fine all day. Get back to my home, phone still on H, works fine. Hops on the LTE network here, Facebook and play store dead again. But they worked on the LTE network in a different area. I give up rofl

[Q] 3G networks not detected on 4.4.4 update

I have updated from .230 firmware to .283 via Ota and root is preserved but after the update my phonr cannot detect 3g networks. Before it was fine. Does this happened to any one else?
Sent from my C5502 using XDA Premium 4 mobile app

Can't detect or detects but doesn't connect?
Check the APN list, you might need to select / reselect / add APN.

It doesn't detect any 3g network at all 2g is fine and I am in area where multiple 3g networks are available. BTW I am from India and in .230 firmware it was all fine.

I have frequent disconnects but that could be network related. I am on 3g most of the time

Like genieass said It might be network related. I only offer a suggestion.
Did you try Settings > Wireless and Networks > Tap "More" > Internet Settings? Just tap it and wait a few seconds

The phone cannot detect 3g networks. 2g is fine 2g data is fine. But when I switch to wcdma or GSM/wcdma on network mode it cannot detect 3g networks at all. It just shows no network even though 3g is available. Trying manual searching for 3g networks is also showing no 3g networks.
Sent from my C5502 using XDA Premium 4 mobile app

I am speaking of data. If you are talking about proper 3g, I might have misled you. You seem to be looking for 3g calls etc? if so, pl ignore me.
My connection is 2g, data is 3g. I am on H+ most times. Firmware updates are faster OTA, 3G than wifi. Which connects thru a 512 mbps dataone adsl line.

The phone simply cannot detect 3g networks. The data part and Internet settings comes after the phone detects 3g networks. So no its cannot be done. When I am on wcdma only setting the phone doesn't show network ie I am on emergency mode. If I try manual searching of networks it doesnot show any 3g network even though I am in a coverage area with multiple 3g networks.

Open up dialpad and type in " *#*#4636#*#* ". Inside "phone settings" you might be able to adjust to some options which might work.
Restart your phone and confirm that the modification has been lost.
Unfortunately it is reset every bootup. So you might want to fallback to 4.4.2 (hack, or 4.3) and wait for solution from Sony.
Post the result of this to Sony Mobile Official Forum might help. Anyways, please report back after trying each option.:good:

After my update to 4.4.4, I lost the ability to access the Internet over my mobile network. I had full signal and even hdpda/hspda+ sometimes but no Internet at all. I realize its not the exact same issue but they might be related. I found out that my APN had been changed when I updated, so I hit settings>more>Internet settings and it fixed the problem. It didnt need to be connected to the Internet to do it either, it just worked on the same network connection that wasnt giving Internet. Hopefully this works for you too, since this caused me endless headaches when it happened.

Yeah but for me no signal when in WCDMA mode just shows emergency mode but when i switch to gsm mode it shows full signal. My APN are automatically downloaded every time i insert my sim card in the phone so APNs are fine asthey are auto downloaded on 2g. But no 3g signal even in full signal strength area. Seems like I have to do repair by PCC which i am trying to avoid as my internet connection is slow. I'll post if the repair is helpful. I was just trying to know if anyone else have the same problem or not.

If all suggestions here failed, then I am quite certain that either your network provider has a problem or your phone has a FW issue. Provided that you dd not fall the phone carelessly and damaged the modem, i would recommend you go search on google for this issue with your network provider on the search keywords. If no luck, Just downgrade to 4.4.2, then report to Sony as a bug.
Anyways, Good Luck
