Here's some scientific analysis: Re-do the speedtest in DC during off-peak hours (11pm, 3am, 5am) and see if you have increased speed. If you do in most often of these cases it's a case of congestion plain and simple if the speed tests were in the same location. Try doing a set outdoors. It's already known in the tech media that VZW is ALREADY experiencing congestion <2Mbps in HIGH population density areas of the US (LA, SF, DC, NYC, etc.) The solution for this is increasing cell site density (building more cell sites) or adding capacity using AWS which VZW has already activated in parts of NYC. Sometimes the only solution in these cases is to wait until VZW adds more capacity. You can get a more accurate confirmation if the CSR's I believe send it to their network team which will tell you a definitive answer (and yes it's congestion and it's already occurred in Manhattan for example).

Read more carefully and the FAQ on T-Mobile's website. T-Mobile's FREE international data roaming is limited to 128Kbps. That's SUB EDGE speeds. Hey it's free but if you can live with that then you're fine. It's enough for text/email and maps. Forget about video and any multimedia. T-Mobile, like Verizon lets you purchase data packs to enable full speed roaming on HSPA+ networks worldwide (LTE roaming is not enabled yet) with T-Mobile being the value leader in the costs ($50 gets you 500MB of FULL SPEED data roaming for 2 weeks, that's more than 2x the amount you get on VZW. AT&T's costs are in the middle.) T-Mobile's TRUE innovation is unlimited text messages while roaming internationally and 0.20/minute in the same 100+ countries. I know people who will get a T-Mobile plan just for the cheap international services (calls and text, occasional data) and they use Verizon/AT&T domestically.

That would require VZW to certify the device on its network based on its current network policy of getting hardware manufacturers to include the VZW specific 700MHz band on its network. I don't see VZW's LTE bands in the specs. You CAN however use that device on AT&T's UMTS/HSPA+ network in the US. I don't see 1900MHz so no T-Mobile unless ASUS has a misprint (most of these devices also have 1900MHz allowing it to be used in T-Mobile's refarmed/upgraded areas).

Verizon uses CDMA and LTE technology and does not use GSM/UMTS technology so therefore VZW does not sell SIM cards or phones not sold by them on their network. The only GSM networks in the US are AT&T and T-Mobile and they have prepaid offers. Please note that most prepaid offers like T-Mobile or AT&T in the US are limited by data volume. Or you can use a 3rd party MVNO riding on AT&T or T-Mobile's networks. Please also make sure that your phone must has the North America 850 / 1900 bands for 2G GSM/EDGE, 3G UMTS/HSPA+ and 4G LTE (AWS or Verizon and AT&T's proprietary band). These are different than the Europe/Asia/Rest of the World 900/2100 Bands. If you want better signal / more capacity on T-Mobile you need to have a phone with a North America specific 1700/2100MHz AWS band (not likely to be on phones not sold in North America unless you have a Google Nexus, or a Nokia Pentaband phone etc.).

The 4S when unlocked by VZW per VZW policy only allows non-US SIM cards to work in it. To get it to work on US SIM cards requires methods that are prohibited to be talked about here. You can Google if you want that info. Hint: It requires using a 3rd party SIM or changing the iOS software. The VZW iPhone 5 is truly unlocked out of the box including US SIM's. Please note that it is carrier specific in terms of LTE bands (its split between AT&T and VZW) so the best unlocked you will get is AT&T HSPA+. Easy way: Upgrade to an iPhone 5. Hard way: Modify your existing 4S.
