After reading a lot of messages regarding the annoying "message from network" popup's and tricks about how to disable them, I have a different question.
First of all I am a HP 6915 owner. With the SIM card provided by my local carrier I can *NOT* receive cell broadcast messages (all other phone functions are working well). It is a 64kb SIM card, but the same type of SIM card from other carriers as well as old type SIM cards with 16 Kb storage from the same carrier do receive and display broadcast messages perfectly but they are not available anymore. Technical support of the GSM carrier and HP blames each other without any solution or suggestion.
Any help appreciated..

Hello,
Apparently I can't store contacts without a sim card in my D2G... Is there another reason that I need a sim??
How can I use the phone without the sim chip? Because my old provider was a GSM but now I'm using CDMA. I figured that I didn't need the chip but then I tried to store a contact... bummer.
So... is there a "dummy" chip I can get or do I even need one? If I absolutely need a chip then how do I get another one?
Thanks!
You don't need a SIM card to store contacts. Default contact storage can be chosen, and from what I gather you're on Froyo firmware as Gingerbread doesn't offer the SIM as a contact storage option.
Make sure you have a Google account configured on the phone. If you do, consider doing a factory reset.
Yup. I'm running Android 2.3 (Gingerbread).
So now what??
Thanks btw!
Have you configured a Google account at all?
I have often wondered why we even have sim cards in our phones(I understand gsm needs them yadda yadda yadda). When I unboxed my phone, a long LONG time ago on froyo, I was playing with all the "features" and could never access the sim card. I thought it would be a great feature for backing up contacts etc.
I think I read somewhere though that sims, at least for the bionic, are tied to ONE device ONLY and could not be swapped between phones. Obviously this would defeat th entire purpose of the card. No?
I am on verizon in the USA only (no overseas travel, no need for gsm) with a D2G. I just kinda seemed odd...

That's plainly wrong.
A USIM card, or rather, an UICC (USIM is a sub-species of UICC, just like CDMA's RUIM cards) contains a small CPU that runs the USIM (for GSM) or RUIM (for CDMA) program. That program is responsible for encryption, key generation, and such.
Unlike Verizon CDMA phones, GSM phones, and CDMA devices using RUIM cards do not need to be flashed to a carrier. All identification data is stored on the UICC.
UICC can be bound to a phone, but it can only be done on the carrier's side (binding UICC's ID to the device's ID — IMEI for GSM or MEID for CDMA). A phone can be programmed to only accept UICC cards of a certain carrier (that's what carrier-locked phones are).
Verizon's CDMA/LTE devices like the Bionic have to use USIM cards because LTE is basically 4G GSM, and you need USIM for GSM codecs, encryption, security, etc. Verizon's LTE USIM cards will not work in non-VZW phones (well, maybe they can provide data connectivity for GSM/LTE phones that support VZW's band; and once VZW moves voice and text to LTE… you get the idea).
Vice versa, GSM USIM cards will (probably) not work with VZW LTE phones as they're most probably locked to VZW USIMs.
DROID2 GLOBAL (and DROID3 as well), however, has a GSM/CDMA transceiver which, once unlocked, will accept any GSM USIM card (extremely old plain SIM cards — which you probably won't find anywhere anymore — won't work well since 3G-capable phones require USIM explicitly).
As for contacts backup, it's a bad idea. USIM contacts storage is extremely limited. You can only store something like 16 characters for contact names, and one single phone number for each contact. SIM memory is also limited; usually you can fit up to 250 contacts with 150 being the average limit.
Note that SIM contact storage can be disabled on the SIM card itself. I wouldn't be surprised if VZW's Vodafone NL USIM cards come with on-SIM storage disabled.
I hope this answers most of your questions.
No it doesn't really help...
See, I accidentally threw away/misplaced my SIM chip. Now when I simply even click on contacts it just doesn't work... literally nothing happens.
I do have a Google account configured but if I choose to import contacts or save them to Google it seems that EVERY single email address I've replied to, or written to shows up in the contacts list.
How can I configure Google to simply store ONLY phone numbers and not every single email address/phone number that I've emailed or texted?
Seriously it's sick that when I sync contacts my list is filled with like thousands of addresses and numbers.
Perhaps I'm doing it wrong??
Thanks!
Well, you don't really need to import anything.
Open https://google.com/contacts in any browser you like (f.ex. on your desktop PC) and check My Contacts there. That's what Android syncs.
So if you get straight talk, you have to select from 4 SIM cards to pop in, and that activates your phone on that particular network... I get that. Lately, however, I've seen multi-network MVNOs arise (like Defense Mobile, ROK Mobile) that only use one SIM card. How does a single sim card authenticate between several carriers? How does a single sim multi-network MVNO handle that extra step Verizon usually requires of authenticating the individual phone's IMEI with it?
Please help me understand.
Thank you.
Hi,
I have a dual sim phone (AOSP 7.1.1 based Vernee Thor) and I have a small issue with my SIM cards. It is more or less just a cosmetical issue and not a functional one ... nevertheless annoying and probably of interest for more then just me, since it is related to a generic issue with SIM cards.
I have 2 sim cards from different providers. For SIM1 the number is not displayed unter SIM1 properties. SIM2 has a different provider, it displays the number under SIM2 properties. As far as I have invented so far the number has to be stored in SIM contact's entry #1 to be displayed, so this is missing for SIM1. Unfortunately I have not found any technical solution how to add/delete/change entries on SIM's contacts. The SIM toolkit app for the Dual SIM phone will not even display the contacts of the SIMs, the standard google contacts app can only export the SIM entries to a file, but can't import it. MyPhoneExplorer will not fix it. Also playstore apps can't deal with this issue - or at least I havn't found one.
I have found solution attempts that rely on old iPhone3 or old 3G mobiles (e.g. Nokia, Ericsson, Sony, ...), but this is all not based on Android and I do not have either an old iPhone3 nor any of those old 3G mobiles..
Is there someone around who has a solution how to get this issue fixed? Thanks a lot in advance!
Hi!
First, let me tell you what I did before:
A while ago I was on a longer trip to a far country, meaning roaming charges were extreme. Luckily my provider offers a VoIP service using the SIP standard, which I can use to make and receive calls with my regular phone number. So abroad I purchased a local SIM with several gigabytes of data included, removed my original SIM and installed the new one, installed a SIP cliant app, configured it to my provider account and that's it. I was reachable on my regular number, as if I were home, for a very small price. Could call enyone and they would see my regular phone number as the caller. Even SMS worked.
Now, the SIP service is being phased out by my provider and "replaced" by VoWifi (aka WifiCalling).
That works if I find a WLAN, but what can I do elsewhere?
Can I again get a local SIM and use it in a dual SIM phone (if I understand correctly, VoWifi does not work without the original SIM, so I must keep it in the phone, unlike for the SIP method above).
So, VoWifi would use the mobile data of the other (local, therefore cheap) SIM, instead of WLAN. Does this work?
I could carry with me another phone, insert the local SIM into it and turn on a hotspot, then connect to it with my primary phone, but then I would need to carry two devices, charge two batteries etc...
Is there a simple solution that would work? That is: one phone, cheap calls (the provider charges VoWifi calls as if at home country, local data only SIM are usually 10 USD per month or so), using my regular phone number for outgoing and incoming calls

Hi there, I need help determining if I was screwed by the carrier. Here's the story (keep in mind I'm in a third-world country where law is more of a concept than a reality):
A few days ago my carrier started calling me incessantly and leaving messages. Being a disabled person, I was not able to answer the calls or listen to the messages. A few days passed and suddenly, the phone service has stopped. This is a dual-sim card phone (OnePlusX) and the second sim card/phone service still functions. The phone also detects the sim card and able to read info from it (such as the phone number associated with the non-functional sim card). The web site still lists my service as active but towers refuse to provide network. When I contacted the phone company, they insist the problem is with the sim card, that it suddenly has stopped working - or the phone did. In either case, they demand that me, blind, immobile disabled person show up at their office to get a sim card replacement.
I feel that the company has illegally disabled the sim card access to their network - that's exactly what the phone say, when I enable the sim-card, that the network is inaccessible. I did try the sim card with another phone with the same results (no tower access and yet the second phone can see the phone number on the sim card) although there's a caveat - law in my country requires registering phone IMEI with the sim card, i.e. that sim card can't be used in any other phone (or even the different slot in the same phone, tried that too, btw).
Anyways, I strongly suspect that the company representatives that tried to contact me shortly before the service was cut were trying to sell me something and when I was not able to answer, they took it as a personal affront and retaliated by disabling my service by refusing access to the network to make me walk back to the office. Either that, or they decided that I'm dead since I'm registered as a disabled person with them to qualify for a special service plan that I barely use anyways. Either way, they probably broken a law or two and now, when I try to make them re-enable my service, they refuse to do so without forcing me to walk into the office and pay for sim card replacement.
My question is: are my suspicions have any real foundations? The problem is, if the sim card was indeed faulty, why would they start calling me prior to it dying, and why would it still communicate the information such as phone number to the phone if it was faulty? I can't even listen to those messages now since the access to them is gone with the service. Any suggestion or additional hints on what I can do to prove or disprove my theory are welcome.
