Does the T-Mobile SIM card for Sprint customers improve phone service? (Well Explained!) 

To this, there’s no yes or no answer. Some Sprint/T-Mobile attest that after the merger, the overall phone service has increased drastically whilst others attest that the service has spiral down from bad to worst and wished the merger didn’t occur in the first place.

Though complaint such as poor phone service has flooded the T-Mobile/Sprint webpage after the merger, both firms have worked ceaselessly to address these issues but yet persist in some locations. Representatives of both firms came out to make a statement, thanking customers for their patience and assuring them of a better service that the problem was location-specific.

The quality of the network coverage depends on the network of your area and congestion. T-Mobile is using sprint’s network as a way to deflect congestion on its network in some areas, especially those with high congestion and high cellular network demands.

One customer that switched recounted his experience: “I have two Sprint lines, one of which I just switched to T-Mobile Sim card, I have taken time to observe both Sim cards. I observed little difference in speed in practical network use of the two on LTE, the T-Mobile sim would provide access to a 5G network but my Sprint will not, and on overall I have a better phone service with Sprint than with T-Mobile over the years.

Moving customers who were on the old modern to the new advanced model with high-speed network, means that those customers must have the enabling phones or devices that can access the latest technologies. To this end we partner and support our customers throughout the transition process. We first began by sending a notification last year to give them an advance notice. Mobile reached out to those customers, explaining the switch, the merger and how it would bring about better next service.
