T-Mobile Was Not the Problem with Twitter
Twitter has been having problems with T-Mobile USA customers having the ability to use Twitter's short code to send messages to Twitter (as noted in T-Mobile Shows Ignorance Blocking Twitter. But, as it turns out the problem for being able to use short codes was not T-Mobile, but was the messaging service Twitter uses to handle its messages. This highlights a couple problems with what happened: 1) Messaging service providers need better communication with customers; 2) T-Mobile was not blocking, but assumed it was.
Messaging Services Need to Improve Customer Service
I know quite a few people whose services for mobile access in the United States use messaging services to handle the SMS for them. All of them (about 7 of them, all in confidence) have said they are not fully happy with the service provider, but the options are rather thin. The two biggest complaints are poor communication when problems arise and maintenance (setup, managing, and monitoring) capabilities. The services are mostly companies who have built applications, servers, and network access to ease the sending and receiving SMS text messages to augment existing services. This is a tough market space to work as it constantly is changing and the costs can be high and staying on top of all the changes takes constant watching (policies of carries and settings change relatively often). What is missing seems to be a service that is proactive and works in a more transparent manner (alerts and metrics when errors happen).
T-Mobile Customer Service Still Good, but Management Reacted Oddly
Let me start by saying I was relieved that this problem was not T-Mobile blocking Twitter short codes, as that would have been a strong reason to move from T-Mobile. The last five years and more, I have been extremely impressed with T-Mobile's customer service. When I have a problem they answer the phone quickly or respond to e-mail quickly and immediately start working on solving the problem. I rarely have problems with their service and the odd occasions when there are problems (like getting international data roaming for a fix rate on my mobile that they do not sell) they work hard to get a great solutions and always seem to go the extra mile. This is one company whose customer service I am always quite impressed with how I am treated, the effort that is put in to provide an optimal solution, and the amount of time (relatively short when compared to all other telecom (mobile or landline - including cable)) it tasks from beginning to final resolution. T-Mobile is my measure for nearly all other customer service I receive.
What is really with the T-Mobile responses did not seem to come from Customer Service (who was not aware that there was a problem, which is slightly problematic but often attributed to a limited knowledge management application to handle trouble tickets), but came from T-Mobile management. There were quite a few people who e-mailed and escalated their problems with T-Mobile and received an [paraphrased]it is our right to block services as we see fit policy response from the management. This is quite problematic. One is that they can and will block services without notification. Second, they respond in this manner with out looking into the problem (this is incredibly counter to my experiences and I would not be a fan of T-Mobile were this the usual practice of ignorance and laziness). It seems that T-Mobile USA senior management needs to take a good look at its own practices and start learning how their customer service is done in the trenches and start replicating that as quickly as possible.
