SIM expert needed. 7520 - 7100i

[kimholle]

I bought a 7100i on Ebay, thinking I got a great deal because the seller mislisted it and there wasn't many bidders. He listed it as a "7100i like new conditions" in the descriptions. He didn't say much else. Unfortunately, I got it today without a SIM. I know there is a pretty big size difference between the 7520 and the 7100i, but is there any other reason I shouldn't use my old SIM? How badly will the size difference affect me? Will it cause problems with my applications or the amount of data that I can store?

Thanks

Your SIM is used for your phone number and contact list. I don't see how the 7520 SIM would screw up your 7100i applications. The only thing that MAY be limited in terms of storage would be your contact list, but I have never heard of anyone filling their address book.

To be able to send or receive MMS messages from the 7100i you will most likely need the 64k sim that the 7100i comes with. I have yet to hear of a CS rep that will provision MMS services to a 32k card. If you don't care about the ability to send or receive MMS, then using the 7520's sim won't negatively affect you at all.

[myownminerva]

the sim on the bb is not used for contacts unless you manually copy them there from the hd. the problems occur because the 7520 is a 32k sim card and the 7100i is a 64k sim card therefore they are not compatible. it may work for a few days but will constantly give you problems.

Huh? The BlackBerry does not use the SIM to store the contact list.

No, it won't constantly give you problems. Other than what I stated in my previous post, the 32k sim will work in the 7100i. Same as a 64k sim will work absolutely fine in the 7520/7510.

[nb_mitch]

The SIM only contains your phone number & numbers you may have put on it with a Non-BB phone, but the address book on a BB is not stored there at all. I can copy SIM phonebook numbers from the SIM to my addressbook on my 8700 but you can't write to the SIM from a BB, so the size doesn't matter.

Your bigger concern would be if the device was locked to a different provider or was on a BES and has a IT policy that might restrict your usage.

How would I know if the phone is locked? I put my 7520 SIM into in and it connected and I was able to make a phone call. However, it said SIM error right below the "Nextel".

[kimholle]

Does Nextel have more than 1 64K SIM? Will a SIM from an i830 fit in a 7100i?

Theres nothing special aboyut a BB sim card its only used to carry service thats it nothing more thats why they used a 32k one no reason to slap a bigger one in therethe bb models 7520 and earlier have a special bb sim card with bb software installed in it. Even if you get the correct sim type for the 7100 it may still give you problems until you get the correct sim card with the correct bb software installed on it. I recomend seeing a service and repair center to see if they have one they can sell you.

[kimholle]

Thanks, Dawg. But then why do I get a SIM error if I put my 7520 SIM in the 7100i?

Like Dawg and I have said many times, there is no difference in Nextel sim cards other than the number of contacts that can be stored on it, PERIOD. If your phone is having an issue, make sure the sim is not damaged and works fine in other phones as well. It could also be the contacts on the phone, so try a different sim in the 7100i as well. The sim cards do not have special software or anything like that at all, that is simply not true at all, regardless of phone model. A sim card is a sim card is a sim card.... The i830 sim should work just fine in the 7100i assuming both the phone and the sim card are in working order.

[akkording]

My 7100i got here today. I will be doing the 7520 to 7100i upgrade and hope I don't have any problems

[Dawg]

The sim card that was in my 730 I put in my 7520 no probs i put it in a friends 7100 no probs i put it in a 930 no probs so I know it works

[kelvin]

We had a user in our are who upgraded from the 7520 to 7100I. He was instructed to install the SIM in the 7100I. It woudl not work at all. They finally gave up and sent a new 7100I.

Wow, Nsupporter, do I wish I had read your response about 5 hours ago. Customer care told me I could use the 7520 SIM in my new 7100i. WRONG!!! I got the JVM error 545 and had to go to a service center where they sent my phone in. Thankfully I have service on my phone, so it won't cost me and I will get a fixed phone back, but now I am going to be stuch with a 7100i without a SIM still. Does anyone know how to get a 7100i SIM? I guess the people who are able to use the wrong SIM in their phones are the lucky ones...

Wow, complete bullshit gets posted and people believe it.... Simply amazing. If anyone believes this bs about sim's try to find hard evidence, first hand, of a phone ever being shorted out due to a sim. Besides that, JVM errors have to do with the Java software that runs the phone, and has to do with a damaged operating system. There is absolutely no correlation whatsoever to using a different sim in the phone, and I challenge anyone out there to prove it. There are thousands of Nextel and GSM customers out there that use their Sims in different devices every day without a problem.

well said martin Nextyel told me my 730 card would burn up my 7520 I used it for two years and not one issue

Thanks Dawg, it makes me upset to see people come here and post complete, worthless, unproven crap when some people out there are trying so hard to help educate people (using actual facts) about blackberry.

[fsager]

Ok I did a little bit of an experiment. I used RSS to read the sim of my i860, then I swapped that sim out for the one in my new BB. From what I can see after using a hexeditor to compare, there was not much diffrence. In RSS, there were some diffrent service flags, but it has to do with the features of your phone line and data service. I couldn't see anything that would affect or fry my phones hardware. Furthermore, I was able to use all the features of my i860 with my BB sim.

So my advice is, use a sim that you may have from another phone. If that doesn't work, then try to obtain one from a service center or corprate store

my 2 cents, eventhough I only had the BB for a week.

**EDIT**
Now that I think of it what do I know. I don't work for any phone company, just an office supply store.

[seebeexee]

The information found here has been helpful. I would just like to add my two cents that are based on fact and actual experience. I just recently bought a BB 7100i. It uses a 64k SIM card. I had previously been using an i930 which uses a 128k SIM card. FACT: The 128k SIM is NOT compatible with the BB or any other phone designed for a lower-capacity card. I know, I've tried... The part numbers on the SIM itself are not the same. HOWEVER, the 64k SIM I used a year ago in an i830 DOES work in the i930 AND the BlackBerry. So, using a 64k SIM in any phone designed for a 64k or 128k SIM is just fine and there will be no SIM-related problems. The only SIM issue in any Nextel phone is trying to use a larger-capacity SIM in a phone designed for a smaller-capacity SIM. The phones are backwards-compatible with smaller SIMS.

While the 128k sims may not work in the 7100i it is a plain and simple fact the Nextel's 64k sims will work in phones that were originally designed for the 32k sims. For instance, the 7510's and 7520's were all issued with 32k sim cards, but will work just fine with a 64k card (FACT).

Now that I think about it, I am almost positive I have heard of users putting their i930 sim in the 7100i and not having issues as well. This thread should seriously be closed before the amount of mis-information and heresay is spread beyond this....

[akkording]

Question for everyone. Just curious what nextel service centers do when you have a 7520 and want to connect a 7100i you bought online. Can they clone my 7520 sim contacts to work on the 7100i sim card that i bought used with the BB?

[Mr Pink57]

They can copy the contacts over on the sim, and active the new card. If you have NSP aka ESRP they will give you a new sim free of charger under ESRP.

As far as the sim war goes, I have put my 128k sim in a i90c, i95cl, i710, i730, i530, i285, i265, i860, 7520, and 7100i all without issue. Only difference of course is in the Condor Series I cannot view my contacts nor add to them I also cannot use txt messaging in some older phones that do not support MMS. Other then that I get service fine, and sure my sim is starting to wear out, but that's due to so many sim swaps a day lol.

[akkording]

I have in my hand a T- mobile sim card cloner. Do you guys know if this will work before I try it?

[Nsupporter]

Well you can choose to do as you wish.

[martin_j001]

^^And if it was really the truth don't you think RIM and Nextel would want their customers to know that, and release said "info"? Come on, don't be ridiculous. Why would a 64k sim from an i860 work perfectly fine in a 7510 then? Why would the 7510's "special sim" work perfectly fine in other condor series phones. Come on, enough with the crap, this is just getting stupid now.

Mods, don't you think now would be a good time to close this thread, as its already gone far enough? You'd think this place would want to keep a reputation of providing the truth and factual answers to people, not allow people to continue posting things like "I know what I'm saying is true, but I can't post why and I have no documented information as to why and my company doesn't want that info out there." This is just getting stupid now.

[akkording]

FYI the clone sim card deviece errored out on me. Let the truth be told.

[rebeldevil2003]

i work for a gsm service provider (which shal remain nameless) and i have personally never heard of any sim from any carrier that has special programming for certain devices. as a matter of fact i have a big box of sim cards that are all made by the same mfg and i put these sims in all of the 20 phones that i sell, with no issue. i have personally had my sim card in 3 diferent pdas and 4 diferent phones and have never experienced and problem. try to do a software update on the bb. also get a new sim from your service provider. if the phone is new it might work better with a newer sim i.e. 32k or 64k.

hope that helps

maybe you just bought a defective phone on ebay, isn't that a possibility? you said that it has been malfunctioning in one way or another since you got it right?

[CBR900RR]

Should there be a SIM standard, just like (USB,DVD,wi-fi,cd-rom,electric outlet etc....), it is suppose to be universal, what if I take my BB to other country and use the pre paid card.

[martin_j001]

EXACTLY. This is entirely possible, and even most likely--ESPECIALLY if the phone has been malfunctioning in one way or another since it came out of the box....

If there were a difference in sim cards you would read about "phones shorting out" and there would be warning stickers and labels all over everything--the carriers would be REQUIRED to do this if they know about it. For a carrier to know about this issue and not inform its customers is simple negligence on their part, and some people are doing carriers a dis-service claiming what they are....

[Dawg]

I am using a 64k card in a 870 thats was designed to have a 128k card nextel service center told me it wouldnt even power up with that card in it. And if it did I wouldnt be able to use any of the phones features. Well i have used it for a month now and have used every feature on the phone. So other than size there arent any differences in sim cards thats a load of BS. Keep spreading it if ya want to

[rebeldevil2003]

The only thing that i can think of is that it is a nextel specific problem. Nextel is still using the iden network as far as i know. correct me if im wrong. maybe this is the issue. as far as i know any gsm sim card will work in any unlocked gsm phone, pending that the model of the phone is compatible with the size of the sim card i.e. 64k 32k
