Get 3G (or LTE) Internet connectivity while you travel overseas.
-Be well-connected, well-informed while you travel.
-Be independent of weak hotel WiFi.
-Locally, for mini coaches/Uber/taxi fleets to add value.

The difference between having data and not having data is analogous to this 45 seconds funny Expedia commercial.

Disclaimer

Most people know that when traveling to another country, they can buy a "local SIM card" to avoid ridiculously high roaming charges.
Most people also know that their phones must be "unlocked" if they want to use a foreign SIM card.

With an unlocked quad-band GSM phone and a local SIM card, you likely can get voice capability and ridiculously slow 2G (EDGE) data.
However, if you like decent data speed, two more critical issues need to be addressed.

Critical issues of 3G frequency band compatibility and APN settings are often ignored, resulting in disappointment and waste of money. This article outlines some suggestions to fix the problem and focuses on obtaining 3G/LTE mobile data when traveling outside your home country.

These are useful references to see if your unlocked phone will work with the carrier in the country of interest.

When you travel overseas, you can choose to be on (1) Phone mode or (2) Tethered mode or (3) Mobile Hotspot mode.

Phone mode (easiest to use and understand)

own
Disclaimer

Europe and Asia:
For Europe and Asia, the phone must be unlocked and have 3G 2100 MHz [Band 1] (and 3G 900 MHz [Band 8] would be nice).

USA and Canada:
For AT&T (USA), Rogers and Fido (Canada), the phone must be unlocked and have 3G 1900 MHz [Band 2] and 850 MHz [Band 5].
Note: T-Mobile US rural and WIND Mobile (Canada) use 3G 1700 MHz [Band 4] which is not used elsewhere. To fix that problem, T-Mobile US aggressively added 3G 1900 MHz [Band 2] and LTE 1900 MHz [Band 2] in most areas. In North America, the term 4G is often used, it really means 3G on steroid. 4G in North America should not to be confused with LTE. LTE has an incompatible protocol stack with 3G.

Visit http://willmyphonework.net to find out whether your unlocked phone will work in the country you are traveling to.

To manage mobile data consumption
-Turn off media sync:

It is highly recommended that you turn off media sync (pictures and videos) to a cloud because these sync will consumer large amount of data, unless you are in a hotel with unlimited WiFi.
-Turn off app auto-update:
Android's default behavior is that it will automatically update app when new ones are available, you may want to switch it to manual update to conserve mobile data.
-Turn off apps that consumes large amount of data. Rumor is that Facebook App consumes large amount of data.


Tethered mode (very similar to phone mode; one SIM for multiple phones/tablets)

hybrid
Use any unlocked, globally capable 3G phone.
e.g. Motorola E 2nd Generation Global GSM phone (XT1505, 2400 mAH battery) has 2100 MHz (Band 1), 900 MHz (Band 8), 1900 MHz (Band 2), 850 MHz (Band 5).
Motorola XT1505 is a globally capable 3G phone.

Pros:
Tethered mode has an advantage that you only need one SIM for multiple phones/tablets and the other phones do not need to be unlocked.

Cons:
Tethered mode has a big disadvantage that some carriers will not allow you to do "tethering", that is, while mobile data can be used on the XT1505 itself, you are not allowed to connect another device via WiFi Hotspot. Carriers typically use "deep packet inspection" technology to detect such a violation.

To manage mobile data consumption
-Turn off media sync:

It is highly recommended that you turn off media sync (pictures and videos) to a cloud because these sync will consumer large amount of data, unless you are in a hotel with unlimited free WiFi.
-Turn off app auto-update:
Android's default behavior is that it will automatically update app when new ones are available, you may want to switch it to manual update to conserve mobile data.
-Turn off apps that consumes large amount of data. Rumor is that Facebook App consumes large amount of data.


Mobile Hotspot mode: (e.g. mini coaches, taxis)
Suitable for (1) locked phone and/or (2) phones that do not have the correct frequency bands and (3) multiple tablets/phones simultaneous use such as family road trip or on mini coaches.

Because some carriers require a phone to dial a special sequence to activate/use the SIM, mobile hotspot is not user friendly for most travelers.
Mobile hotspot should be used for special situations.

Mobile Hotspot in Europe and Asia:

For Europe and Asia, the Mobile Hotspot must have 3G 2100 MHz [Band 1] (and 900 MHz [Band 8] would be nice).
A low cost entry level Huawei Mobile Hotspot E5330 can be used. It has 2100 MHz and 900 MHz.

Mobile Hotspot in Canada:
For Rogers and Fido, the Mobile Hotspot must have 3G 1900 MHz [Band 2] and 3G 850 MHz [Band 5].
Huawei E5377s-32 can be used as a 3G Mobile Hotspot in USA, Canada, Europe, Asia. It has 3G 1900 MHz and 850 MHz.
Huawei E5377s-32 has LTE Band 7 (2600 MHz), it works with Rogers/Fido LTE in Canada (see below about APN settings to get data to flow).

Huawei E5377s-32 "Universal" Mobile Hotspot:
Huawei E5377s-32 is a new generation of globally-capable 3G-4G-LTE mobile hotspot. See this specifications page (PDF).
E5377s-32 has the four 3G bands for global roaming (1900 MHz, 850 MHz, 900 MHz, 2100 MHz).
E5377s-32 has six LTE Bands 2600/2100/1800/900/850/800 MHz [Band 7,1,3,8,5,20]
Huawei E5377s-32 has a 1500 mAH battery yielding 6-hr working time. By adding a small 2600 mAH external power bank, you can extend it to 12 hours working time or more.
An external antenna with a TS-9 connector and appropriate frequency bands can be used with the Huawei E5377s-32 to increase the signal strength for stationary or vehicle applications.

To manage mobile data consumption
-Turn off media sync:

It is highly recommended that you turn off media sync (pictures and videos) to a cloud because these sync will consumer large amount of data, unless you are in a hotel with unlimited WiFi.
-Turn off app auto-update:
Android's default behavior is that it will automatically update app when new ones are available, you may want to switch it to manual update to conserve mobile data.
-Turn off apps that consumes large amount of data. Rumor is that Facebook App consumes large amount of data.

*For Hong Kong CSL, you need to dial a special code to activate a data pass. Huawei E5377s-32 cannot do dialing, hence Mobile Hotspot is a bad choice for Hong Kong CSL, however, Mobile Hotspot can still be used, but only after some excessive geeky tweaking.




Mobile Hotspot Battery Issue:
Typical mobile hotspots have a battery life of 4 to 6 hours. Higher end hotspots have higher capacity battery that can last up to 10+ hours.
For small battery hotspots, one strategy is to turn on the hotspot only when you need to access the Internet. Another strategy is to use an external USB power pack to power the hotspot for extended operating hours.

For mini coaches applications, you can connect the mobile hotspot to a USB power source using vehicle power. An external antenna with TS-9 connector and appropriate frequency bands can boost the signal when moving on the highway. Not all antennae are the same, check carefully the operating frequency bands of the antenna before buying.

Future Issues

SIM cards may disappear one day and be replaced by e-SIM which is not removable from a phone.
There is a movement in carrier and mobile phone manufactures to eliminate SIM card and replace them with e-SIM.


Mobile data for traveling in USA

Traveling in Canada

Phone:

Make sure your phone is unlocked and has 3G 850 MHz [Band 5] and 1900 MHz [Band 2] or else you will be wasting time and money. A mobile hotspot for Canada should have 3G 850 MHz and 1900 MHz; nice to have is LTE Band 4 (1700 MHz) and LTE Band 7 (2600 MHz).

Using Huawei E5337-s32 in Canada

E5377
For Rogers LTE SIM, leave the E5377s-32 in factory default mode and it will automatically set the APN correctly; E5377s-32 works well on Rogers LTE network.
For Fido LTE SIM, you need to enable roaming and add a profile called Fido-LTE and set the APN to ltemobile.apn,
E5377s-32 only works well on Fido LTE network after the APN is set manually.

SIM cards for use in Canada

Roam Mobility (http://roammobility.ca) You can order online a US$35 plan for 7 days (includes SIM, 500 MB data, voice calls in Canada, unlimited global SMS.
You phone must have 3G 1900 MHz [Band 2] and 850 MHz [Band 5]. Tethering is allowed.
If your phone has LTE Band 4 [not likely if your phone was bought in Asia/Europe], that would give you LTE speed in major Canadian cities.
Roam Mobility seems to be the best option for travelers to Canada.

Similicious does not support mobile hotspot mode.
The service is $55 for 500 MB data & voice (Canada wide) or $45 for 500MB data with voice (one province only).

Petro-Canada Mobility SIM card can be purchased online for $10.
$15 Monthly Plan includes 25 minutes of voice, unlimited Canada-wide SMS, add $15 for 500 MB data. There is a $1.25 "911 fees".
Summary: $41.25 gives you 25 minutes voice and 500 MB data.

Fido Data SIM: If you have a trusted friend in Canada with a (post-paid) monthly Fido account, your friend can get a Fido-SIM and a "Data Plan for Mobile Hospot" (aka Flexible data plan) added to his monthly bill. The Flexible data plan is $10 for the first 150MB, $25 up to 1GB. After you leave Canada, your friend calls Fido to cancel the plan, your friend may face a mildly irritated (but polite) Fido agent because your friend started and cancels a "plan", it is all above board & played by Fido's own rules. Getting a Fido SIM provisioned must be done at a Fido store and is very time consuming.

Roam Mobility Data SIM (http://roammobility.ca) has a $27 plan for 7 days including unlimited voice calls in Canada and 500 MB data.
You mobile hotspot needs to have 3G 1900 MHz [Band 2] and 850 MHz [Band 5]. If your mobile hotspot has LTE Band 4, that would give you LTE speed in major cities in Canada.
APN setting for this new service is probably sp.telus.com  (not yet confirmed).

Prepaidzero data SIM uses Rogers mobile network. Follow the instructions that come with the SIM card to set APN in the Mobile Hotspot and turn on data roaming if you are using Phone mode. APN setting for Prepaidzero SIM in Canada is rogers-core-appl1.apn

Bring a pocket WiFi router when traveling

g
A TP-Link "TL-WR802N" or similar WiFi router can be used to convert a wired-Internet connection to WiFi.
Why? Some hotels still provide legacy wired-Internet connectors. In situations where there is no WiFi, or in-room WiFi is very weak, a pocket WiFi router offers a tool to deal with the problem.
