Default Unlocking a Cingular 8700C for overseas travel?

Please Login to Remove!

Hi, I recently took a job that requires travel to Europe and Asia. I'm thinking about moving from Verizon to Cingular for enhanced global support. If I want an 8700C, I'm under the impression I would need to unlock it for use overseas. If true, what are my options? Thanks in advance.

bongo, i'm sure. although they most likely won't offer the ability for some time after the release date. heck, being cingular, they may offer it unlocked anyhow out of the box. you should really just wait until the phone is actually released before asking such questions though, as no one really knows much right now.

Time out

Shipspeed - do you just want to use the BB overseas, or do you want to put in a SIM card from another carrier? If you just want to use the BB overseas, using your existing SIM card, then all you have to do is call Cingular and make sure the account is set to allow International roaming. If you want to put in a foreign SIM card, then you may have to contact Bongo Wireless.

Will you be abroad long enough to want to have complete BB service from a foreign carrier? If not, do as NJBB says and pay Cingular the extra $20/mo for unlimited global data, then get a local phone+SIM for voice. If you'll be going to several places, your options are to either pay Cingular's high international voice roaming charges, get a SIM for everyplace you go, or get a SIM that has lower-cost international roaming. A cheap unlocked phone from ebay is all you'd need for voice coverage.

Out-of-North America BB services could force you to get a new hosted BES/MDS provider + deal with customer service that could be even worse than
Cingular's. I thought about this for an upcoming 4wk trip, and it was a very poor option for me. If I were going to be gone for a year, I might have to think again. You might want to get a different BB, since things like EDGE + US based OS might not do what you expect with an overseas provider.

This wouldn't be an issue, because most EDGE data devices (BlackBerry and otherwise) are generally backwards compatible with GPRS. Thus, the 8700 would just behave like an older BlackBerry when travelling overseas. Would be no problem for data roaming at all.

Using a foreign SIM will probably render your data capability useless unless you subscribe for that service. Turning on the GPRS will probably eat up your Prepaid SIM load. Besides, BIS devices are provisioned to a particular carrier and if you want to switch carrier, you will have to request that your device PIN/IMEI be transferred from previous carrier to new carrier in order to work. I have gone through this process in the past and it took about 5 days before the BB got activated and working.

As previously posted above, if you're travelling over short periods of time, you may just want to have your carrier activate your service for international roaming.

shipspeed, I am an admin with at least 25 bbs in Europe and Asia at any given time, we sent a bb with Cingular over there to test and they have no coverage there. You would want Tmobile.

I've traveled in France and Germany in 2004 and had no problem using my bb. I have a 7280 with Cingular. I received and sent email with ease. I would place a call to Cingular before you go however in case your account needs to be modified in any way.

Interesting as I have no problem with my Cingular 7290 anywhere in Europe. Coworkers' Cingular units work fine in AP as well (excluding Japan of course)

You have to have Cingular add International roaming to your account. It works fine in Europe then. I have used mine in Europe on several trips.

I appreciate everyone's replies... I have done all of the suggestions mentioned. We were told that Cingular's international coverage, had surpassed Tmobile's. Hence the trial. I have international bb's customers reguarily, not just with blackberries, we use a variety of comms equipment, from bb's to thuraya's to satelite phones, as I support USAID and the Dept of State. Their coverage just does not rate to Tmobile's.

and yes, my thumbs hurt...

If you have the quad band BBs it really doesn't matter whether you are on Cingular or T-mobile unless you are in an area exclusively covered by T-mobile and no one else. If your device lacks the 900MHz band, then the T-Mobile devices will give you coverage where the Cingular devices lacking the 900 MHz band will not. With Cingular, you are roaming on other European carriers (you must have International roaming service on the account or nada). With T-Mobile you will be raoming but on their network most of the time but not always. (I have also traveled to Europe with a T-Mobile device and service). It is a little easier with T-Mobile but other than that prety immaterial (I too work for the U.S. government).
