My Requirements

Required:

  • International standards support
  • Reasonable service plan cost
  • Apple iSync support
  • Bluetooth
  • Reasonable hardware cost
Added Bonus:
  • Internet access on my laptop computer via the phone
  • Internet access on my laptop computer via WiFi (using T-Mobile)

My Phone

Unlocked Motorola v620

Standards Support

The phone comes with a USB cable that's compatible with OS X.

My Service Provisioning Experience

I tried to order service using T-Mobile's website but ran into a few issues. I couldn't get the T-Mobile Internet package to show up in my cart unless I added a PC Card modem type of device to my order. Since I planned to use my unlocked v620, I didn't want or need another device.

Then I called T-Mobile to try to place an order but the person taking the order was confused and didn't even know that T-Mobile Internet is $19.99/mo if you order it with a National plan (it's $29.99 by itself). This person also refused to let me place the order with all the options I wanted.

I called a second time after deciding that I would just add the Internet package after I received my SIM Card from T-Mobile. So I told them I wanted the Basic plan (for regular phone calls) and the Worldclass service. The said they don't sell service without a phone, so I was "forced" to get a (free) phone too.

T-Mobile sent the phone and SIM Card which I popped into the v620.

I created a login for My T-Mobile and chose the phone model that's most similar to the v620, which is the v600. However, I wasn't able to active the Internet plan. I guess that's because T-Mobile doesn't want to support it on this phone, which is nonsense. So I chose the Sony Ericsson GC79 card and then all was well. (That card choice was just to trick the website into letting me order the plan I wanted; I didn't actual take possession of that item.) I added the Internet plan and waited until the next day. Service was active in less than 24 hours.

My T-Mobile Plans / Options

Connecting to the Internet

Options Matrix:

Computer-Phone Connection Phone-Internet Connection
USB Cable GSM Dialup
Bluetooth GPRS

Any combination of the above will work, provided you have the correct service.

Combination #1: USB Cable / GPRS (T-Mobile)

This is one of the first things I tried to do with this phone. Even though I didn't have Bluetooth yet, I referenced John Chang's GSM Phone as a Mac OS X Modem page to help me out. Thanks, John! It's very simple — too simple! I tried to make it more complicated and of course failed. All you have to do is open Internet Connect and enter internet2.voicestream.com as your telephone number and then hit connect.

I was behind a NAT gateway where my internal IP address was in the 10.x.x.x range, and the external IP was 66.94.16.25

Combination #2: USB Cable / GSM (T-Mobile) to Speakeasy Dialup

I actually used the Motorola iR TimePort (7089) script that's supplied by default with OS X. It works fine. The other settings are just regular dialup settings that I got from Speakeasy. Connecting using this method works just like using the built-in modem... but the speed is an abysmal 9600 bits/s. You better have a lot of minutes to burn.

Combination #3: Bluetooth / GPRS (T-Mobile)

This works fine and the speed is the same as #1 above.

Combination #4: Bluetooth / GSM (T-Mobile) to Speakeasy Dialup

Haven't tried this yet, but I expect it to be very similar to #2.

Observed Data Speed

Downstream
Test file size: 2,193,856 bytes
Transfer method: HTTP
USB/GPRS average throughput: 2,652 bytes/s
USB/GSM Dialup to Speakeasy average throughput: 906 bytes/s

Upstream
TBD. Um, not expecting much speed.

Non-U.S. Net Access

Here's an unknown for me: non-U.S. Internet access. I hope to test this soon, which as an added benefit means a nice trip! According to T-Mobile's International Internet Services page, I can pay 1.5 cents per KB ($15.36 per megabyte!) You have to manually select the correct service provider on your phone to avoid using the wrong network. Otherwise you have to pay per minute as well.
Update: went on a trip, but just used a local broadband connection.... The link in the paragraph above is broken; I tried to find a replacement link but couldn't. It's easy to find the per-minute rate for international Internet access for a particular country, but I suspect there's still a data surcharge per KB somewhere.

Non-U.S. Voice Calls

Went to Barbados and inbound/outbound calls worked fine for both local calls within the island, and calls to the U.S. I was alternately roaming on either Digicel or Cable & Wireless Barbados.
Or they now have cruise ship roaming.
If you're going to Japan (where GSM won't work) you can rent a phone from T-Mobile or lots of other places.

iSync

Under 10.4, the v620 can sync with iSync using Bluetooth. You just go to the Bluetooth preference pane, set up your phone, then open iSync (which finds the device automatically).
Apple's iSync Device Compatibility page. [Obsolete: under 10.3, you had to use the USB cable with iSync.]

Fax

Yeah, all this tech and let's send a fax. I haven't made this work yet, but I'm looking at some options: sending, receiving 1, receiving 2. Also, I need to try again with Bluetooth. Possibly I need to call T-Mobile and pay $10/mo for the "CSD (circuit switched data) option" (ref). More wild but potentially helpful rambling.

Sending
OS X 10.3 sees a device called usbmodem1B11 or /dev/cu.usbmodem1B11. It dials out but then gives up before the receiving end even rings.

Receiving
OS X 10.3 won't answer incoming calls. Apparently this can be hacked (see links above).

Overall Pros / Cons of My Setup

Good Bad
Internet Cost $20/month unlimited
Internet Speed 2.5 KB/s (observed)

Mobile Tech Pitfalls

AT&T Wireless has an unlimited data plan, but then charges you $1.02 per megabyte to get the data from your phone to your computer. They are being folded into Cingular and this info may be out of date.

Joi Ito ran up a $3,500 tab in one month using GPRS roaming. Great illustration of how we are "not there yet." I'm not sure what that means, but when we're "there," I'll know.

Todo

See about recording conversations using the headset jack. Need to be able to listen, talk and record at the same time. Must output to line or mic-level 1/8" phono plug. Headset is 2.5mm plug. This Wireless Phone Recording Controller from Radio Shack ought to do it.
