Leasing

How do I get a number?

Aerialink is a number sponsor which allows you to lease a number in a matter of minutes.
Dedicated short code numbers require registration with the Common Short Code Association (CSCA) and cross-carrier certification with all wireless carriers. Aerialink will guide you through the steps regardless of what type of number you need.

How long does it take to activate long-code numbers?

It’s instantaneous via our Platform or our API.
If you desire special ranges, let us know. We can generally activate these within one-to-three days if they are available.

Absolutely.
We also support special location-neutral long codes that do not resolve to a known area code.

Porting

Can I port to/from Aerialink?

Yes, provided that porting is supported for the long code, which is true of most (but not all) cases.

My long code is getting telemarketing calls. Can you put it on a “do not call” list?

The business that leases the numbers manages this aspect.
This is similar to leasing numbers from a telephone or VOIP carrier/service provider for your voice lines.

Text-Enabling

You bet we can.

Is it a problem if the number’s currently in use?

No problem at all.

Why can I call my 11+-digit vanity 8XX number, but not text it?

Voice network number translation matches numbers progressively while mobile messaging matches numbers exactly.
In other words, the actual “number” that we text is only that first ten digits (plus the country code!), and any additional digits entered will make the number unrecognizable to your mobile device.

Mobile Messaging

When sending A2P traffic internationally, what “from” number or name will be displayed on a device receiving an SMS from my application?

This varies by country.
The displayed “from” address could be a fixed, Aerialink-leased long code, a short code or a customized alpha/alphanumeric (e.g, your company name). In some countries, the original sender ID may get overwritten by a local ID to avoid carrier blocking. Please enquire for specific country restricitons.

Short codes are country-specific
Message delivery from a U.S. short code is intended for U.S. destination numbers operating on U.S. carrier networks. Non-U.S. numbers will not receive messages sent from U.S. short codes. U.S. end-users with American handset devices and numbers roaming on international networks may be able to successfully receive messages, but this cannot be guaranteed.

Compliance

Do all carriers follow the same requirements for message flow and content?

Their base requirements are the same, but additional expectations differ.
While all mobile programs must uphold the guidelines set out by the regulating body for their country (CTIA for the U.S., CWTA for Canada), carriers each have their own, additional set of expectations which must be fulfilled by mobile programs wishing to send to that carrier’s mobile subscribers.

Where can I view the CTIA requirements that all U.S. carriers follow?

Right here.

Aerialink has no self-generated, additional requirements for compliance.
Short code certification is subject not only to following the CTIA guidelines but to meeting carrier requirements which are applied in addition to what is recommended in the CTIA. Aerialink’s certification team stays up-to-date on the latest industry standards, best-practices and carrier requirements and has compiled these all together for your perusal in the Compliance section.

Compliance expectations vary not only by carrier, but by carrier employee.
Not only do carrier expectations change frequently and often go unpublished, they vary depending upon whose desk your program brief has landed on. It is very possible that your message flow was rejected based on either a new, unpublished requirement, or because the carrier-employed individual who reviewed your program brief has interpreted those requirements in manner differing from what Aerialink has encountered in the past.

Short Code Migration

Still curious after reading our Leasing & Aquisitions articles? Let us answer your questions.

When does carrier migration actually happen?

The time of migration varies by carrier.

Do I need to schedule my migration?

No. Most carriers migrate at their own rate and require no formal migration date.
Two carriers—Sprint and T-Mobile—do set migration dates, however no action is required by you, the customer. Aerialink will notify you of when your carriers have migrated.

Do carriers migrate in a standard order?

There is no standard order by which the carriers migrate.
Each one will review, approve and migrate your code at their leisure.

How long does it take for a carrier to start and complete the migration process?

The length of migration varies primarily on how busy the carrier is.
Once your program brief is submitted to the carriers, it is up to each carrier to review and approve your short code. If their compliance and certification teams are very busy, it may take longer to review and approve your code.

Do Tier 1 carriers migrate first?

Migration time varies for Tier 1’s and Tier 4’s alike.
Tier 1 carriers typically take longer to approve and migrate a short code to the fact that they have more programs to review at a single time. However, if they are not busy, Tier 1 carriers can migrate just as quickly as any others. Aerialink has seen Tier 1 carriers migrate first, last and everywhere in between.

How will I know that a carrier has migrated?

Aerialink will provide regular status updates throughout the migration process.
When a carrier has migrated your code, Aerialink will notify you via email.

Will MO’s and MT’s be switched at the same time?

Traffic will switch prior to carrier migration for MO’s; after migration for MT’s.
MT’s will continue to go through your old aggregator until migration is complete.

Aerialink can provide you with a temporary long-code number.
The temporary LCN may be used for traffic or testing while migration is occurring.

When can I start testing?

Aerialink will confirm when each carrier has migrated and is ready to be tested.
Aerialink will proactively test your code on Tier 1 carriers in addition to your own testing.
